Hi! So first, the guitar I'm going to paint is by no means a good one. It's by C. Giant and I got it litteraly for free from the street. It's not broken tho, and it has a nice enough sound to have some fun with it when hanging out with some beer and stuff at the river with friends. So I want to customise it a bit, but I am not sure what/ how much paint it can handle. Can I sand of the current varnish? Or cover it with a thin coat of a new varnish? I am gravitatimg towards acrylic paint/ acrylic markers, since they are easy to apply without much per to any surface, but I have anything from watercolour to oil painr around soooo xD And again, doesn't matter if it looses a bit of sound quality, but I don't want it to be completely unplayable :)
