That's funny, I took a picture this morning just to show you guys, at http://home.hiwaay.net/~langford/04022110m.jpg , which shows the tube of stuff and the "measles" Bob described. It fills 'em up, and sands very easily. Our body shop teacher said something like "don't bring none of that Bondo junk in here", and told us to get "real spot putty from the auto paint dealer", but I've been using this stuff up until now and I think it'll work just fine. It IS polyester based, which is famous for shrinking, but I can't see that something this tiny is going to shrink enough to make a difference. You have to prime over it, other wise there will be a "dry" looking spot, as it is more porous than the surrounding primer, and it will definitely show. Just throw one last coat of primer over the top of it when you're done, and then sand the last coat of primer with 400 grit, and paint it.
I don't really think this is the way to fill ALL pinholes, but for the few that might get past peelply, or some other method, it seems to work great as a second line of defense. I still can't complain about Smooth Prime, as it seemed to work for me, but I suspect that some of the other primers would work just about as good, if worked in with a roller like Smooth Prime is. Even Urethane 2K is $85 a gallon, but I think it would work too, and I'd bet that it'll be more compatible with urethane based paint than the water-based SP, and it certainly won't have the water absorbtion problem that was mentioned a few weeks ago...
