I am an artist and I play an old beaten up Yamaha TRB5. I like the aged and battered look of it but I have never been keen on the orange finish. I am thinking that it would be nice to paint the thing with doodles. I expect that such a painting would take a time but it is my only bass and I can't go without playing it for long. How long would it take to sand the finish off? Would a base cote of white acrylic paint be enough for a temporary cote whilst I paint it or would it let moisture in? Would it be possible to sand and then paint it section by section? I don't mind it looking a little patchy. Actully, I was thinking of leaving the orange on in places. As I say, I don't mind it looking a bit crap - I am going for character here. Thanks for any help.
