I just stripped my truck and parts with abrasive blaster crushed glass and have started to apply the Eastwood After Blast but have some questions about application. The directions say spray on and wipe off but the panels are left with some weird texture and look blotchy when done. I am using blue shop towels to wipe off. What am i doing wrong.
Also, after after blast is applied can I apply my Bondo directly over or do I need to sand down. I was planning on sanding down with a DA 36 grit but do I need to fully remove the after blast.
