Working with a swamp ash tele body from warmoth and i have some questions about sanding after grain filler. I see most using 220 grit. Is that as fine as i want to go? I see some saying to sand back to wood, others saying that defeats the purpose, as you might expose more pores. So what do you think? How “deep” should i sand? What should the surface look like before i move on (not sure if I'm going to sanding sealer or straight to the blond lacquer i have). Dull, with no scratches? I did some sanding with a small block and some 220, and i got to flat(no shine) but there are still visible scratches. Unrelated question: whats your solution for sanding the sides(not sanding sanding sealer specific, just general), particularly the inside curves? I don't have a spindle sander and I'm not really into buying one, so cheapo sloutions are appreciated Thanks for your thoughts.
