Paint blasting

I'm looking for opinions on which is the best media for removing several layers of paint. I'm currently using glass beads which does a wonderful job on rust or thin paint. Could I have some of you guys' expiriences please.

Are you doing a large area or small parts?

I use recycled glass in my blasting cabinet and for nooks and crannies after I chemically strip the body of the car. The chemical strip I use is https://www.acklandsgrainger.com/AGIPortalWeb/WebSource/ProductDisplay/globalProductDetailDisplay.do?item_code=DSSSSO

Just know though that it takes off one layer at a time. it is virtually odourless but will sting/burn if splashed on bare skin. I have really like it.

Aircraft paint stripper in the blue and red can. It is expensive, smells like ammonia, burns if you get it on your skin. It is the best product on the market. Around here it is only avaiable at auto body wholesale.

I am amazed that the EPA still allows it to be sold. IT WORKS! Google it.

I've had good luck with Zip-Strip Chemical stripper. It's in a black and Yellow can. I worked in a boat shop for years and every other paint stripper we tried when we couldn't get our stand by was a joke.

I used aircraft stripper like Curti uses on a a station wagon before and that did perform well to. I know your local hardware probably stocks Zip Strip. Try both and see which you prefer. Same thing. Burns and stings the bare skin. Be sure to neutralize the acid when you are all done so you don't get a chemical reaction under your new paint.

I've used this stuff and it's amazing. Just don't keep it around too long, after a year it ate through the steel can.

I to use the aircraft stripper, far superior to the crap the big box store promotes. And yes, you are right the bottom will eat out. I made a small box that a half gallon glass container will fit in to protect the glass against breakage. After my initial use of the stripper I pour the remainder in the glass jar. Remember the old acid carboys, same reason for my storage. --Bob

I usually start with a more mild chemical stripper like Citristrip. It has to sit longer, but usually does a good job on the old lacquer and enamel finishes. If that fails, I'll move up to the nastier Methylene Chloride types.

We have a do-it-yourself sandblasting facility in our area with different blasting cabinets and different media. The one that is excellent for quick paint removal is walnut shell. No chemicals! After the paint is removed, a glass bead or more aggressive media can be used for rust cleanup or prepping of metal for painting.

Maybe I didn't make my original post very clear. I was talking about blasting mainly smaller parts or whatever will fit in my cabinet. I have used chemical strippers for years, but recently bought a sandblast cabinet. ckowner has the idea of what I am asking. Does walnut shells come in diferrent grits? This is more of what I am asking. Sorry for any confusion. I was very tired when I made the post.

I'm not sure if walnut shell comes in different grit. It really doesn't matter. Walnut shell takes the paint off quickly and aggressively, but does not touch the metal. I have used it to clean paint off old wire wheels. Since our local facility charges by hourly use of their cabinets, it is very important to use the one with media that is most effective.
