I'm getting ready to coat my first SOF kayak, and I'm wondering:

A) Is there anything I should do to prep the skin for coating? If I was polyurethaning wood I'd wipe it down with solvent and let it dry before coating. I'll probably at least vacuum/dust off the thing before coating.

B) What's the general strategy for coating the entire boat? I'm thinking paint the bottom, set the chines on blocks with polyethylene on em and then do the deck. Should I wait for one side to get tacky before I flip it?

It's skinned in polyester and I'm using exterior polyurethane to seal it.
