I find that SSR2.5 finishes down pretty well, so you shouldn't have any trouble on a light colored car, anyway. It does have some fillers or something in it, however. I don't know that SSR2 really finishes down any better, so SSR1 if you have it, or you can try the consumer version of 205...what is that, SwirlX? IMO 80 isn't going to be much different than SSR2.5.
