Great for getting into those areas that sheet paper can’t reach. 320 grit takes the shine off for painting epoxy very well.
Just discovered this great net sandpaper. Seems to last better and doesn’t clog so easy, easy to clean too. Only you need to have longer rolls.
The best and easiest way to send the walls without any dust. I have tried other brands,nothing is even close to Abranet Ace Sanding discs.
