I'm not looking for a full paint job, I just want to touch-up some bad spots on my tank. Translation: cheap home remedy with no expectations of perfection. It seems sound, but I patched a pinhole on the bottom, so I suspect it may end up swiss-cheese; thus - cheap. It's original factory gold and white paint. I know that certain paints shouldn't be mixed, and matching the colors will be a pain. Anyone have any suggestions or paint brands/models that work? Or is this a case of all-or-nothing?
