Powdercoating

[TexasPigHunter]

i am being told by a few different companies that you can powdercoat over existing powdercoat, does this sound right? or should i have it stripped and whats the best chemical stripper? trying to get my new ranch hand coated to match my truck's trim. thnx

if i remember correctly, powercoating is done with heat. I would be affraid if they reheated it with the new color, it may mix

I wouldnt poweder coat over it with a different color, its adheards to the metal and with the metal not bare it would come off rather easy, exspecially with it being a bumper. Id have it sand blasted, if its worth doing, its worth doing right

i used to powdercoat, and it is used with heat, it gets baked at about 400 to 500 degrees. it is a plastic type powder that when heated, it melts onto the metal creating a really good bond.. i dont think a chemical stripper would be very effective at the removal of the old powedercoat. i would not recommend coating over an existing color, you would have to have it sand blasted to remove the old coating and recoat with the new color.. hope this helps.

well thanks for the replies, not what i was hoping to hear but its what i thought was right. cant afford $500 to have it stripped and recoated, they only wanted like $150 to just recoat. whats the best way to remove the old coating(brand new bumper still in packaging) for the DIY?

well there were two ways we went about it.. we burned the coating off of our hangers then used hydrochloric acid to clean that, or sandblasted them.. most of the parts needed to be prepped in a solution after blast to clean and etch the metal being coated. i think it was a phosphorus/water mix in a dunk tank if i remember right.. you can try a chemical stripper if ya like, but it may take a while.. or you could use a sanding wheel too. but that is a lot of work..
