so i just got my plate filler but i need to paint it, and i got some questions. what grit should i go down to. i should wet sand it correct? and i was thinking of doing it in a can of touchup paint from autozone, would that be ok? how many coats should i put on? and for clearcoating, how many coats and can i use a regular clear coat or do i have to get an automotive kind? because i already have a can of glossy clear from krylon that i picked up at walmart but dont know if thats what i should be using. sorry if these sound like stupid questions, its the first time im painting anything exterior and dont wanna screw it up lol
