Exit1965,

Are you sure that brightside "has better gloss after wetsanding and polishing"?

The reason I ask is because I spoke to the Tech Rep at Interlux and he said that the gloss in brightside rises to the top and that the paint is not meant to be wetsanded and then polished. (Hence the high level of intitial gloss.)

Conversly, the Tech Rep at Rustoleum said that their paint can be polished because of the resins present throughout paint.

I am not a paint expert and I don't play one on T.V., I just thought I'd share what the company reps relayed to me. I'm sure there's someone here that can expalin the difference in the paints' composition - if a difference even exists.
