There's some really awesome stuff called POR-15, but you can only get it online (I think), and it's spendy. But, since you only have a couple spots, I wouldn't bother ordering it (unless you have other project cars or something). I got my stuff at the local auto parts store...it shouldn't be more than $10 or so. It's pretty common stuff, so you shouldn't have problems finding it. Make sure you have a small paintbrush, too.
