I recently purchase a guitar body that had some finishing problems (drips, uneven finish, a few bare spots, small divots in the clear coat around some areas, a neck pocket that had hard checking that's already begin flaking... and a curious sharpie mark). Without getting into the details, I'll mention that the seller sent some extra paint so I could restore some of the more egregious areas. I taped off the areas and added the new paint. After a couple days of drying, I noticed it's definitely a lighter shade of paint they mixed up than the original coat. I'm not too worried, but I am curious about a few things: How long after applying the paints should I wait before taking off the frog tape? Is there anything I can apply before the clear coat (perhaps a slightly tinted oil) that would seep into the re-painted areas to darken them just slightly? Is there something like a thinner or something that can kind of "melt" the paint slightly that is easy to apply that would be good for the blending process? Is there any technique in buffing that could be used to blend the colors better, or do I need to wait to buff until after the clear coat? If I need to level down the areas where paint's been added before the clear coat, should I wait a couple weeks to sand with a super-fine grit to make it level, or should I do that sooner? Will an untinted clear coat darken the paint at all or help make the new areas look more "muted" and normal? Thanks for the help. I've only worked with finishing a few times, so I'm still a bit of a novice. Any details would be appreciated.
