'Naval Jelly' is the Brand name. I think it is owned by the Loctite Corp. now.
Here's a link to it at Ace Hardware, but It's no longer owned by the Duro Co. , like the Ace pictures show. That sold by Ace is the original formula. I've been able to find it at a much reduced price on eBay, but none presently.
They increased the price recently and I can't find it in large bottles anymore (which cost less per oz.), probably when Loctite took over. <img src="http://forums.aaca.org/images/graemlins/frown.gif" alt="" />

My local Wal-Mart carries it. Klean-Strip Rust remover "jellied rust remover"
Product #WRK37. It comes in a plastic 8 oz. bottle.

Klean-strip and Naval Jelly are Not the same thing. Alto I don't remember useing Klean-strip, I doubt that they are the same formula. <img src="http://forums.aaca.org/images/graemlins/crazy.gif" alt="" />
Naval Jelly is the original formula, developed for the US Navy, during the '40s, to kill rust on Naval Ships.
Several years ago I tryed another brand of gell, but can't remember if it was Klean-strip or not, and it didn't work half as well as NJ. Had to put on several coats to get same effect as one coat of NJ.

Permatex also sells a 'look alike' rust dissolver. Both their label and bottle look similar to the real Naval Jelly. I've never tried it. It may be the same with their label on it. Most other products sold by Permatex are good, so it may be worth a try.

I've searched high and low for what you are talking about and cannot find it anywhere. I used the Dupo brand Naval Jelly years ago and this stuff works just as well. Phosphoric Acid is the active ingredient. The jelly base is just a carrier.

I've started a new post containing the tutorial on surface rust removal. It would no doubt get lost in this thread.

I received the Clausen products 'Lighten-up' and 'Smooth-out'.
The Lighten-up is very similar to Bondo filler (same hardener, setup time, etc.), maybe it has little finer solid material in formula. It works great. <img src="http://forums.aaca.org/images/graemlins/cool.gif" alt="" />
Adding the Smooth-Out Really Improves the way it goes on for thinner applications. It converts the Filler to a Glazing-putty, which allows you to use the same filler for All needs, depending on how much Smooth-out you add. Great Stuff! <img src="http://forums.aaca.org/images/graemlins/smile.gif" alt="" /> I added it to Lighten-up and to Bondo and It works great with Both. <img src="http://forums.aaca.org/images/graemlins/smile.gif" alt="" /> You have to be careful, and add it in small amounts tho, to get a feel for how much is needed. Which is the only problem I'm having with it, knowing 'how much to add' to how much filler.

BTW the Clausen Lighten-up cost less than Bondo, and the gal. can was Fuller, which makes it even more cost effective. <img src="http://forums.aaca.org/images/graemlins/smile.gif" alt="" />
