Sanding Question
Posted: Fri May 03, 2013 1:45 pm
Yesterday, I finished sanding all the old finish off the back of the 00 I'm building. If you don't remember, I started spraying finish and after 3 or 4 coats my compressor broke down, then after getting it up and running I was a little panicked and sprayed coats too close together and got sags in the finish, and then I ran out of finish before building up enough coats. Finally, I sanded through the thin finish while trying to level sand the sags I had created. Bummer. So I decided to sand everything except the side back down and refinish. The sides look pretty good.
It took forever but I finally sanded through to bare wood removing even the z-poxy pore filler (not sure if that was necessary). The mahogany back looks nice but with a light at a low angle I can see scratches that are roughly 45 deg to the grain. While the finish/zpoxy was still on I sanded every which direction. But I sanded with the grain (220g) for quite a long time near the end.
So should I worry about these cross grain scratches? I really don't want to remove any more wood from the back but I will sand more if the cross grain scratches will show up under the finish. What do you think?
