I'm going to try painting a ghetto guitar with spray paint
I got primer with black car paint and polyurethane semi gloss.
Can I just spray over the finish thats already on? do i need to use the primer?
How many coats of color should I put on?
how long should I let dry before I spray on the gloss and buff?
I tried the spray on a scrap piece of wood and I'm liking the color. And I tried sanding it with some 320 grit a day later and it made the color dull, was this too rough? i have 600 grit but i can get finer if i need to from a hardware store. and would it still come out a nice and glossy?
