I am in the process of doing a color change and am looking for the best approach for scuffing the engine bay. Everywhere I can I have been scuffing with 600 grit, but there are numerous nooks and crannies I want to make sure I scuff as well as I can that are difficult to reach with sand paper. Is there a mild abrasive I could load into a spot blaster that would be effective for this? I don't need to go to bare metal, I just need to make sure I have the best chances for proper adhesion over existing paint.
