I had these doors custom made at BarkerDoor and unfortunately, they’re just a hair too big because they’re sticking when you open and close them. I tried using a belt sander to take a little material off, but I don’t think that’s the right approach because it didn’t make much difference. To be safe, and avoid them sticking in the future, I think I probably need to take 1/8” total - what’s the best approach for this? I primed them, but they’re not yet painted, so I have some flexibility.
