I bought a used Fender Jazz from Guitar source a few weeks ago that the last person had ****ed all to hell, there were scratches on the body and the person took the pickguard off and spraypainted it silver. Since then i have most of the spraypaint and original black finish off so it is a real dull black color. I was going to have it painted white when i got the cash but having the strings adjusted today at Spencers (local music shop) the guy there said i could apply paint stripper and it would take ALL the finish off and it would be the natural wood color. The paint stripper can also said this. After about 3 sprayings of the stripper it still looks like the same dull black, no paint is coming off. the can says some paint takes longer, should i let it sit overnight? does this even work? please help!
