to strip or not to strip?

#1 Can you powder coat over exsisting powder coat without stripping off the old powder ? The new powder is a different color than the base coat. #2 If the old powder does have to be stripped first ,will steel shot damage the base metal aluminum? Thanks in advance.............John

yes you can coat over the old pc but not recommended...., I would suggest you strip the item and recoat. as far as the steel shot I cant say cause Ive never used it.

If you leave the old powder on I would use steel wool or 220 sand paper.

I get things steel shot at a local machine shop and haven't had any problems so far.
