So I am doing a belly flop into the pool of refinishing guitar bodies. Last fall I bought a $50 Sawtooth ET guitar off Walmart.com. This spring I got the bright idea to repaint it a light blue color, and doing some general 'sharpening'. http://www.tdpri.com/threads/sawtooth-et-guitar-sharpening.953260/#post-9184913 I've gotten to the point where I have made my first attempt at spraying the color, in this car Duple-Color perfect match lacquer. But after I sprayed, I see that I can still see scratch marks from removing the old finish. What did I miss? Here is what I've done so far: 1) stripped the factory finish off with 60 grit sandpaper. My initial plan was to scuff the surface, but as I sanded I got through to bare wood in spots. So in for a penny, in for a point and I sanded the whole thing bare. 2) sanded again with the 200 grit paper and 400 grit paper. I think perhaps I should have done a pass with 120 grit? 3) I sprayed two coats of Duppli-color filler primer, then two days later I sprayed an additional coat of primer. 4) after 35 minutes, I sanded the primed body, and wiped down with a cloth loaded with windex, 5) I sprayed two coats of Dupli-Color Perfect Match lacquer, and after those, I noticed the very visible scratches still there. The temperatures for all of this was around 80 degrees with approximately 70% humidity. Did I need to do additional sanding on the body to get the scratches out, or did I not spray enough coats of the filler primer? From here, I think I need to sand this coat of paint back, can I then spray more primer, or do I have to go back to bare wood again and start anew? Thanks!
