I'm planning to strip and refinish a cheap-o squier i bought on craigslist to do terrible things to before i screw up a nicer instrument (defret, refinish, rewire, etc). so far the defret and the rewiring have gone great, so now up is the refinish: my question is: can you just "rough up" the original finish without stripping the whole thing in order to keep the primer/base coat intact? i've got a feeling that it might hold better if i do it this way. the stock finish is a god awful electric blue and i want to paint it white, and i'll be using something out of a spray can. thanks!
