Powder coat removal?

[bucky]

The other day I saw a chip of coating on my front bumper. I pulled it off reveling a large area of substantial rust. I did a quick search here and found a short previous post where Chris had a link to an Amazon product but the link is no longer valid. I prefer not do a lot of sanding or sandblasting to remove all of the powder coat. What is a good chemical stripper? I plan to repaint with a hammered finish. This is the most rust I have anywhere on the TJ and am surprised how deep the pitting is.

That is VERY typical of powder coating gone wrong.

All my Chinese armor and fenders are doing that. I plan on having a friend use his big commercial sandblaster some day when I take it all off. Etch prime and satin black for me. Easy to touch up

Replacing the Chinese made bumpers with USA made ones would be less work.

I tried that and must have used the wrong words.

I've tried a few of the industrial PC specific chemical strippers and none of them work very well. My powder coating shops that I use also won't sandblast to remove PC, but will blast automotive paint. They say it takes way too long to remove PC.

The failure of the coating on that bumper is due to improper prep and then insufficient heat/bake time. I know little of that bumper but a good custom PC job on one like that with blast and coat from raw is around 150 bucks.

If you are in the Anaheim area from time to time, I can send you the info on a stripping company that dips. Be around 30-40 bucks for that and it won't have 1 square mm of PC left anywhere.

I've always used aircraft stripper. Takes that stuff right off in a matter of seconds.

I've also noticed the powder coating on the cheap Chinese crap does that too.

I've removed powder coating with Permatex Gasket Remover . . .

Wow. I’ve always thought powder coating was tougher than that.

Aircraft stripper will take off just about anything.

Aircraft stripper will take off just about anything.

Which one in particular?

I couldn’t tell you. It’s been probably 7 or more years since I used it last. All I remember is I bought it at the auto part store and it made short order of the powder coat. Burns the hell out of your skin too.

I just bought some Rust-oleum Aircraft Remover. I see this does not have Methylene Chloride in it any more so it might be shit. Might be another California thing. I’m making a desert run on the 16th and won’t start on this project until I get back. I might have to take a trip out of state to get some good stripper and hammer finish paint that dries in a reasonable amount of time. I have a trip to Az at the end of Nov so I will get it when I’m there. Thanks for the help.

They have pretty much banned methylene chloride nationwide except for a few select industries. It is pretty nasty stuff that really shouldn't be in the hands of amateurs.

I work in labs and use it all the time. It is probably banned in home use products as most chemical these days are known to be carcinogens or bad for pregnancy, or women who plan to be pregnant.

That's what I said, isn't it? Home products is the same as consumer use.
