    stripping powder coating

    Is there any chemical I can get from HD or Lowes to do the job? or is it mail-order or specialty shops only?

    Can you recommend a HD product that will work?

    Aircraft remover will remove it safely.

    Yup aircraft remover. Coat the part, then wrap it in plastic. Keeping it wrapped up letís the stripper stay wet and work longer.

    in stock at autozone, check.

    Does an aluminum part need to be neutralized after stripping, or can I hose it off, then blast with brake cleaner and start installing parts immediately?

    Post up your results when you're done. I've used aircraft remover for powder coat in the past, but they banned the use of methylene chloride in aircraft remover in 2019, and I haven't tried the new formula. I have some parts that I need to remove PC from, but I haven't picked up a can of the new stuff.

    Let us know!

    So, I got the frame I was going to use the rear triangle off of, and it turns out the color is not bad. pics made it look green, but in person it's a yellow more similar to what I took off my bike.

    So I won't be stripping after all.

    Now, I do have the FRONT triangle of a 2004 Jekyll frame that I'm not going to use, and has basically zero value. I don't think I could even sell it on ebay for $40. I COULD technically try the stripper on this one.

    You guys think a part-stripped front triangle has no value? may as well use the paint-stripper in that case..

    OK, here are the details:

    I got the spray can, which, according to the instructions, takes longer to work. 45 min vs like 15.

    My can is the new formula without VOC's

    The results were poor.


    ---------------

    So, I took my junk frame and HOSED the seat tube below the top tube. Then I let it sit for 45 minutes. Then I scrubbed with a wipe. The results are below, "before" and "after".

    To be fair, the spots the paint came off, it completely flaked off, leaving lovely bare aluminum. But I hosed the equivalent of a paper towel tube worth of surface area. So it needs to be SERIOUSLY saturated, or given even more time, or needs lots of repeat coatings.

    My conclusion: not a fun or easy job. Though MUCH easier than stripping house paint off your interior doors....

    Interesting. The formula with methylene chloride definitely used to work, although it certainly wasn't fun. I'm wary of the new stuff now. I wonder what commercial powder coaters are using now...

    Thanks for the response! Very good to know this info.

    Looks like it'll work. Just needs something like 4x the chemical to get the paint off, and 4x the time, and 4x the elbow grease. And 1/4 the fun.
