    What's the best technique you guys have found for getting 1-part poly smoothly painted into tight spaces, like foot wells in a surf ski or around hardware, where a roller won't fit?

    Welcome.
    Try a brush. Wear gloves.

    Touche' :) Foam brush or bristle? Tried with nice angled bristle brush first, but that seemed to leave a lot of grain... haven't tried sponge yet.

    Follow up question: is it practical to do a two-part paint over a one-part?

    You may just dab it on with a natural sponge. No linear brush marks that way; just texture.

    This boat is a beater, so a great boat to experiment on with glass and painting...

    Follow up question: can you do a two-part poly paint over a one-part?

    Try the triangular sponges sold on the make-up isle.

    It it usually not recommended to use a two part paint over a single.
    The two part frequently has solvents that attack most single pot paint. If it doesn't have immediate problems then all is almost OK. You won't get the adhesion benefits of the two part because the over painted single will fail under the two part. Kind of like painting over tape. Looks good until the tape lifts.

    FUNNY, it's almost as though building a boat and gelcoating and painting it is a complex process that requires a great deal of skill and planning. Who'd have thought. :) I sure bumbled into this, but it's been a great learning experience on a found boat. Nothing to lose and turning out a bit better than expected. Lots of things to improve on next time.

    If brush leaves marks; use a capful of thinner.
