Hey, it’s Tony from LearnAutoBodyAndPaint. Welcome to today’s Q&A Series! Here’s today’s question:
“I used 800 grit paper to wet sand a small area on my bumper that had scratches, now I have a foggy spot, I need to fix this area before I trade the car, what would be the best action to take?“
Remember, the higher the number, the finer the sandpaper. I would have actually started with a 1000-grit and then went to 1500-grit then, 2000-grit.
You need a compound to buff this out, compound buffs out scratches in the paint like 800-grit but you don’t wanna buff over 800-grit since it’s way too coarse.
I’d recommend that you start buffing with at least 1500-grit or 2000-grit if you’re doing a black paint job or darker colors. You need to be careful not to cut through your paint because if you do cut through the clear coat then you’ll have an issue.
You’ll needs to use a 2000-grit paper and sand that 800-grit scratch out. Go over that dull area with 200-grit
You’ll need a 2-step buffing process. This means, you’ll need to use a compound to get it glossy. Compound alone won’t get it glossy. You’ll then go over it with a foam pad with glaze.
