I can't believe I missed this thread. :doh: Since Highside has actually painted multiple BOC screens he is a good source of info. Thanks Rob! :T

All BOC isn't the same, some might have a problem with fibers wanting to pop up after priming and others might not. If fibers do pop up it is my understanding that they can be sanded down by using a medium or fine grit sanding sponge, but I have never tried this yet. Have you tried this Rob?

The other thing to be watchful of is having a visible texture difference in the BOC; this might not be much of a problem if using a flat paint, but if you are using a paint with metallics in it (such as our custom mixes here) the different textures will show up in the final screen.

-Sanding with ANY type of medium (I've tried just about anything a former woodworker can) will produce a smoother surface....BUT, the fibers have ALWAYS returned on the next sprayed coat. My assumption is that sanding does nothing more than cut off the fiber, which then grows back with the next coat.

Very interesting, I would have thought the fibers would be gone with a light sanding (like after raising the grain with a water-based stain in woodworking), but it seems not! Very good to know! I know this might not be practical for most people, but I wonder how a scraper would work? Anyway, it's easier to just roll the first coat of primer if spraying. :T

I can add more detail as needed or answer any questions. Hopefully this thread will stick around and people can reference it or post to it as needed in the future.

It can be added to the forum index.
