I've noticed white raised panel doors in many homes and townhomes in our area. They all look pre-finished but when I went to find them at all the local stores the best I could find was off-white doors that are ready to finish. Does anybody know if these are the doors that are used and what method do they use to finish them? I was going to paint them semi-gloss white but I don't think that's what I see in homes and can't picture builders painting each and every door white. Any suggestions are appreciated.
