Yeah I feel your pain. I rushed into colour on an SV-1 without reading up and found all of the problems you have run into. I actually stripped it right back to raw wood, fixed up the surface dings i hadn't noticed and then made some wide sanding blocks to do the whole guitar surface in a pass. It is sooooo easy to ding the basswood, that even dust build up will mark it if it clogs on the paper. For now its sand, clean, spray, sigh and repeat.![]()
