in the proccess of painting my air vents...
i need a little advice... this is what i did so far.
1. i sanded everything down really smooth with 180 grit 3m sand paper.
2. i washed all the sand residue(sp?) off.
3. then sprayed 3 layers of paint
4. now im on my second layer of clear coat. its pretty much dried. but its not so smooth. wassup with that? did i do somehing wrong? any sugguestions to make it a smooth finish??
