I saw a post on here from 2023 of someone using dupli-color 1k clear coat (which is what i’m planning to use), one of the comments said that it didn’t like being wet-sanded but i’ve tested it and i don’t find anything wrong with it does anyone know if there’s a problem with this ?? and also, should i apply decals and metal transfers before or after the clear coat? if after, do i apply them before or after wet-sanding ?
