Currently working on my first refinishing project. I sanded down the front of the headstock, masked off the edges with tape, and then sprayed with reranch's blue anilyne dye aerosol and clear nitro. The edge came out perfectly. I haven't yet done a final sanding/polishing on it, I'm waiting for the clearcoat to dry a couple days. Now my question is, what's the best way to protect that edge where it goes from the original finish (just clear nitro, I believe) to the new finish? I don't just mean while sanding....it feels like the very edge would be very vulnerable to having the finish chip.
Also, I've got a small computer battery for a sanding block like suggested, and was just wondering if I should sand in a circular motion or continue going with the grain.
Thanks!
