Getting ready to paint a new front door and have questions.
I've just bought Sherwin-Williams exterior hi-gloss deep red paint and will start painting this door in a basement room on saw-horses in the next few days. I plan to apply Zinsser Bulls Eye 1-2-3 gray primer first and then put about 3 coats of red paint on the door, sanding ever so slightly between each coat after each has dried thoroughly. So now one question is -- should I use a roller or brush? The door is a smooth fiberglas and obviously, I want it to look as smooth and nice as possible. I used a brush when I painted my interior bannister this same color because it didn't seem to lend itself to a roller. And IF I go with a roller, which kind will give me the best, smoothest finish? ALSO, the between-coats light sanding --- should it be with very fine steel wool or very fine sandpaper or does it make a difference?
