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.
#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

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.
