Alright guys, I had a stripe painted on a Sea Fox CC boat, however the paint peeled and blistered due to the fact that the line was below the waterline from the factory. My plan is to remove all the old paint, and move the line up 3" to have it above the waterline. Whats the best way to go about removing the awlgrip? My fiberglass guy is planning on removing it with 320 sandpaper, however he said he wont blend it for me. Whats the best way, or how much grit should I use to bring the shine back?
