For those of you that use PVC trim, how do you fill in nail holes? I just redid one half of my garage door brick molding, would have done the other side but it looked like a storm was coming in. What I did was caulk the joints and used 15 gauge 2-1/2" finish nails. I left them close to the surface and will just paint over them. Any suggestions on filling the holes? I had one door I did in wood several years ago because the bottom edge was rotting, replaced it with wood. Following year I did the other door with PVC brick molding, filled the nail holes with caulk which shrank. Trim still looks good though. Any suggestions are much appreciated.
