I have a chainsaw case a blasted with glass bead and there are some small spots that still have old powder. They are clean and they are down to powder (nor dirt grime etc.. over them), 25 year old powder is stubborn in some spots. My compressor needs a rebuild (no air) but I need to have this case done soon.
I also read about putting 2 coats of powder on. DO you spray and cure the first then spray another? If that is the case I should be able to blast over some of this old paint with no problems correct?
