Was looking into doing a refin on one of my guitars using the cheap Rustoleum spraycans (2x painter's touch). Anyone have tips? Been looking around for resources and want to know if anyone here had input. I'm not quite sure on time between spraying coats, sanding between coats/different layers, how thick to spray, or even how i should spray it outside to prevent dust/etc (i don't have a shed or garage to do this in) right now i'm planning on doing the following. sanding the body lightly (has an oil finish right now) filling in the chips and dents with wood filler fill in wood grain (ash body and I want an opaque finish) sand til smooth spray 2 coats of primer/base coat scuff with 400 grit spray 3 coats of color (scuff with 400?) spray on 3 coats of clear let cure for 2-4 weeks level sand and polish? any help is appreciated!
