“What sandpaper grit should I use?” is one of the most popular questions on every auto forum. It is important to choosing the right sandpaper grit for each task to avoid paint damage. There are a lot of different contradictory information online that can be very confusing and overwhelming especially for beginners who have never done any repair projects before.
After reading some of the posts, I found out that a lot of car enthusiasts are using the wrong grit. I saw some people were saying that they’ve used 600 grit or even 400 grit sandpaper to repair clear coat scratches. Big mistake! Sandpaper lower than 1,500 grit is too rough for the clear coat and will leave small scratches.
