[pickleboy]

another i have heard about that is supposed to be a good stripper is n-terpinal. have not tried it myself yet but i will be getting a sample 5 gallon bucket soon. will let everone know how it works. only thing is like caswell degreaser listed earlier this stuff has to be heated.

Methylene Chloride is an active ingredient in many paint strippers that are found at your local hardware store, and it works well for removing most powder coatings. Always wear gloves when handling this stuff.

Soak your part for 15-30 minutes and the powder should become clumpy and wipe off. Carefully heating the cleaner about 5-10 degrees above room temp may help to speed up the chemical reaction, as well as wiping the part occasionally to loosen the top layer and expose more coating to the chemical. Use a wire brush or knife to scrape off any powder that remains stuck in the corners. Thick brushable pastes are a good alternative to soaking.

Acetone and MEK are other good solvents, but should not be very effective in removing a well-cured powder. If the coating is made to be very chemical resistant or if the coating is actually anodized and not powder coat, none of the above methods will work. And as a reminder when working with chemicals, you should check to make sure that it doesn't eat away at the metal on your part before stripping expensive parts!

SOLUTION!! Spray the part, then immediately place some GLADWRAP film over the spray. This holds the solvent in, and makes it work on the paint.

These cans are fairly economical used this way, and they certainly get into the awkward spots.

You need to ensure the material you use has the generic name of METHYLENE CHLORIDE. aka 'aircraft stripper'.

If you want to soak something, get NAPA lacquer thinner about $10 per gal, or MEK (Methyl Ethyl Ketone) or a mixture of both. MEK evaporates slower then lacquer thinner.

Also Caswell SP Degreaser, run at about 180 deg f will do a mean job of paint stripping too.

I wrapped a large fan shroud in plastic cellophane after I sprayed it and WOW, the powdercoat came up in sheets. Still....a lot of work in removing all of it though.

Has anybody tried Permatex gasket removal
A buddy of mine sprayed it on his powder coated intake and it came right off
The can is only 4$

Thats interesting. How long did the part sit with the stuff on it?

Needless to say, I am disappointed with it.. The shelf life is not good at all for almost $200 for 5 gallons.. I bought 10 gallons of the stuff.

I have had a wheel in there for over 24 hrs now and it hasn't even started to strip it yet.. It worked good at first... but its not worth the money.

Plus the salesman that I spoke with didn't have a clue why its not working anymore... What a joke..

Need to find something else...

I was an inch away from buying 5 gallons and asked them a few questions about it. One question was about shelf life. The answer was "Several weeks". You got to be kidding me. $200 for 5 gallons of something that has a several week life?

Was that the D-zolve 1012? I was thinking of getting some.

Yea that d-zolve works but cost's to much
I did not know about the shelf life though damn thats messed up!
