Is there a filler I can use to fill over exterior paint used for pmf? Im very satisfied with how the finish turned out except for a couple of areas where the weave us showing through.
I agree, you can add more paint. Also, I don’t think that seeing the weave pattern in some places is bad, unless you know for certain that you just don’t have enough paint on it. My canvas has plenty of paint, yet there are some areas where the weave pattern is visible, I’m not worried, the job looks nice & neat.
If these suggestions are not to your liking, you can try Bondo spot & glaze putty.
