I have the same question as katesherrill.
We are wanting as smooth a finish as possible on our 74' vinyl walls.
I tried using household Goop to fill screw and rivet holes. But, it's stanky-nasty-toxic.
My local hardware guys don't think normal wall putty will adhere to the vinyl.

I'd have to say most of us just fill the holes with rivets the it ties in with the rest of the interior. I use the ivory painted rivets that you get at vintage trailer supply for attaching the interior walls.
