Trying to match Cad colour.....

Recommended Posts

I want the original look but demand the durability of powder coating....so here I am.

I have had a shop powdercoat my frame and other chassis bits but I am doing the stuff that I can fit in a normal oven....

I am trying to match the colour of Cad plating though....I know it is impossible but would like to get close (sans the green blue viens look).

I have never really seen true Cad plating in person so all I can go by are the pics out there. The thing is I think most are paint anyway so I really don't know?

Any thoughts on this:

Yea I have a sample of their powder as well but I think it is identical to the powder I got from 365powder.

If I can't get it to look close enough I will just have them plated...I just like the extreme durability of powdercoating.

Also I can't ship Eastwoods aerosols over the great Canukistan wall.

That looks very good...I would be more happy to powder coat the "faux" cad plating, rather than to try my various other methods of painting to match.

The parts look great! Really good for powder. I agree with Adam.

Bob, if you go back to the 57 Buick thread on the plating for the bolts. As you posted in that thread, Caswell Inc. - Copy Cad® and Zinc Plating Kit they have a cad style zinc plating. They also have a gold cad -like bath for the plated parts as well that will provide that "golden cad / golden chromate look" to the parts. As for me, I went the way of Adam..used the Eastwood paint on the parts. It is all about the technique, and does turn out pretty well for paint to simulate a golden cad plated part, especially if it is a part not in the spotlight. TP Products also has a golden cad style paint as well.

Also, unless I want to eat car parts, the oven is off limits for powder coating per my wife! :D

Thanks guys...

I was worried it looked "cheap" or way off.

I really like the concept of powder coating...it is freaking strong! I looked into the plating kits...I just love the chemistry and fun factor but in the end it was the fact of the expensive rectifier and that I doubt it would be economical to do all the plating myself.

Now that I am confidant that I have the right mix for my powder, I will do the other three plates.

For the record this will be a driver...all the way to the first National after it is done. good.gif

Jim, your project is how I should have done mine....I envy your wisdom in being able to complete your restoration with the balance of doing it correct and complete but doing it in a way that saves time energy and money. Beautiful work, its a model for all of us!

Me I got caught up in the "Might as wells".....

Thanks Bob..those "might as wells" are there regardless of the level of restoration you do, even the driveway style..

Your car will be outstanding when you are completed with it. I can't wait to see more of your in progress pictures, that's for sure. Hopefully, the drive to Nationals won't be too far for you (read: South Bend 2013 :) ). Heck, maybe we could car pool, you basically have to drive through Detroit to get to South Bend! That would be a blast!

Great job and keep up the faith and good work. Your attention to the details really shines through!

Just asking............

If you haven't seen CADMIUM plating, especially on 1950's Buicks, how do you know it's suppose to be gold and not the silver gray?

Very good question....

I have simply followed the lead of some very knowledgeable restorers. These are top notch guys and I have full trust in them when they say that some things are, the way they say they are.

Names not required...just look up the 3 longest threads in the Buick section and you will see who I am talking about ;)

There is also a wealth of 54 Buick info on the 54Buick site....where a MrEarl hangs his hat. He is the one who has a whole garden of 54 Buicks to draw info from.

....just saying pleasantry.gif

Geeze I could have sworn you said they were Gold Cad....

Boy is my face is Red.

Thanks Al for bringing it up....thanks even more Lamar for running out to the barn to clean one off.

I see slight gold hints on mine under where the spindle was installed but its hard to tell for sure. I just assumed the plating was long gone and that's why they were not all gold.

I have to admit, I have been following the 55'ers on this. Could it be that the 54's were silver Cad? I guess I may now find out how tough that powder really is when I have to blast it all off. Good thing I was busy and did not bake the rest.

Fun fun fun eh.....ooops!

I think they look great Bob. I did my 55 with a gold cad "look" powdercoat. I'm not sure what Lamar is trying to show. Mine (55, of course) were gold under the gaskets.

I'm not sure what Lamar is trying to show.

I'm just showing what I found when I took a kerosene soaked rag and cleaned all the grease and grime from a low mileage 1954 Roadmaster set of backer plates. Maybe I stripped the cad plating off but I don't think so. If I were you I'd seek answers from other '54 owners Bob.

curses, now I've got to clean all of them or that spot will stand out like a sore thumb.Maybe I'll just put the grease back.

I'm cool with that Brother, but that is still the exposed portion. I saw no gold color until removing the backing plate from axle shaft.

I will defer to the 54 owners amongst us. HOWEVER, black paint will get you 400 points also.

Just sayin'. There are a LOT of worriers here. My chassis judge was 16.

Respectfully,

It is interesting to find things out when removing things that otherwise would be mostly either hearsay or the dreaded "because thats what everyone has done with it before".

Mike, I, like you, look for the scraps of details that might give us insight into the truth about how the car was built. It is that CSI type of digging and noticing the details that lets us make the correct assumptions on the restoration. There are a number of things that I have found out about the colors and plating on my 57 that I have seen differently on other 57's that have been accepted as the norm. Not saying that it is going to be accepted on the judging field, but it is what I have encountered in my endeavors toward my restoration. Gold cad where others have shown silver, etc. Of course, documentation is difficult at best, since we don't have access to the supplier specifications that were provided to the supplier of choice in the era, and we don't have access to the engineers that wrote the specifications as well.

All we have to go on is what the previous restorer's have done, and in our cases, what we have seen with our own eyes on the dissassembly of our vehicles. Can't say that it is right or wrong. It is what it is.

Geeze I could have sworn you said they were Gold Cad....

If I did I don't recall what would have been the occasion. The last time I remember talking about it was when Fred was asking what color brake drums should be and I took a look at the same 54 Roadmaster and reported that I could find no paint on them but that the brake backing plates appeared to be either zinc or cad plated. Last night I cleaned the grease off the other front brake backing plate and actually found a splotch of bright yellow paint such as would be used for an inspection mark over the gray cad color so I am sure I didn't strip the cad plating and was seeing bare metal. Gold color cad had to come into being some time or another, perhaps it was '55.

Hell just go with the Marine Corp way, when in doubt about what color to paint something, paint the sumbitch green.

Yea I should clarify...I assumed it was Gold when you said Zinc or Cad plated simply due to the fact that I kept seeing the 55 ones and they sure stand out.

I have other Buick things to do...I'll let this one simmer but it would seem that I will be going to Silver. I am concerned about how hard it will be to remove this powdercoat.

Green eh...that sure would make everything a lot simpler!

Thanks all

Bob, I think Eastwood sells a powder coat dissolving solution. Will they ship it to you? It looks like it might be what you need to change the color. However, I have found that the Gold Cad plating also oxidized to a gray coat, thinking that the sacrificial gold surface goes first.

I have found that on a number of items on my 57 that I thought at first were silver cad, and when disassembled - the un-touched by the element surface was gold cad.

That could be true with the brake backing plates, especially since they are very exposed to the elements. Don't fret about it. I think the gold is probably right and again, could be that different parts got different plating from different suppliers. Not sure the quality control was quite the same then as it is now.

By the way, the gold looks better anyway. Gives is a nice contrast. There are lots of silver plated parts on the car, but not many gold cad.

That's my 2 loonies worth!

Cheers!

When I pulled my backing plates off, they appeared to be a very light gold cad color. Nearly silver.

The powdercoat can be blasted back off, but I don't think I would go through the trouble if I were you...but it's your car.

Well the more I think about it I would have gone Silver now based on Lamar's findings but the fact that I went through the trouble to mix my own powder and coat one plate I may just stay this way. I love the contrast as well. Who is to say there was a switch through the year, there are other switches that are correct for both 54 and 55's. Hell I was fooled once by the hood ornament on a 54 Super which was the same as a 53 RM.

I will however hold off for a bit on the other three just in case I change my mind which seems to be as stable as wind direction right now. wacko2.gif

All of the 55 plates I have worked with were gray on exposed surfaces and gold on the protected surfaces. A set of 54 plates that I acquired from a rodder are the same... maybe the car was late production and used 55 parts:confused::rolleyes:

Leave them alone...they are too nice the way you have them now, and like Mike said black will get you 400 points.

The powdercoat can be blasted back off, but I don't think I would go through the trouble if I were you...but it's your car.

As long as it is not the hi-temp powdercoat, you can bake it off in your oven on "self cleaning" mode (which I think pushes up to 900 degrees or so). Having mistakenly coated a part in the wrong color, and then attempting to bead blast it off -- I can tell you it is far, far quicker to bake it off. This is assuming you have a part that can withstand the temperature (please don't ask me how I know *that* piece of info...)

@StealthBob -- what color/brand of powdercoat did you use for the Gold Cadmium approximation? That looks pretty damn good to me. I mixed up a batch of Silver cad using argent silver, blue and semigloss clear -- but it was a hassle and difficult to be consistent.

Did some melting did we.....hehehe

I used 365Powder and mixed 1/2 cup Gold with thin tsps of Silver, Blue and Green each. The neat part is that he colour changes at different angles and light conditions. My first attempts on some practice pieces were waaaay too Yellow gold. I found also that I needed to "Fluidize" rather than mix the powder after combining, I jack the air up and wasted a bit out the gun which really mixed up the reservoir. I also experimented with blasting it off on the experimental pieces...OMG this stuff is TOUGH!
