72 Duster Resurrection

If you sand blast the powder off, it might work ... but you'll probably tear up the surrounding areas too. Whether it comes off at all is going to depend on a well-done job versus a hack job. :D Like painting a car, great prep is everything.

They make Powder Coating Stripper. It's not usually available to the consumer in affordable quantities but you might be able to find some on ebay or something (I get 5 gallon containers for $150 plus shipping here PowderStrip Powder Coating Paint Stripper). If you're "lucky," aircraft stripper can work too but, again, it depends on how well the job was done and whether it adheres. If the parts were completely covered, it's fairly likely it was a rookie job and it might be under- or over-cured which will make it come off easier.

Thanks to @KosmicKuda for the mention! (Phoenix Powder is in Jersey and has nothing to do with my shop by the way ... but your heart is sure in the right place!!!! << hugs >>)
