Boy, oh boy! Those two-part paints require some learning. Finally got a
decent coat on the topsides this morning. Here are some of the things I've
learned:
If the temperature is above 75, don't paint.
Most especially if the sun is shining directly on the surface to be painted,
don't paint.
If it is evening, and the bugs are coming out, don't paint.
Unless you have an environmentally secure and controlled space, pay special
attention to the above three items.
Do not leave off painting before the job is complete (a ridge will result
that is impossible to cover up without sanding)
Do not have more than one wet edge to your paint job at any one time for
same reason as above.
Do use a 1/8" foam roller rated for epoxy/urethane use.
Do thin the paint.
Do recoat within the allowed time window to avoid re-sanding.
I am a fairly accomplished do-it-yourselfer, but were I doing it over, I
would probably elect to use a good one part urethane. The two parts ARE
great paints, but almost require a professional touch to use successfully or
else plenty of time to wait for the exactly perfect circumstances.

Two part LPU is notoriously hard to apply without spraying. Boat yard
people and various articles I've read over the years have consistently
warned that non-spraying applications of LPU are challenging. I think
there are special thinners that make the job somewhat easier, but I would
probably just not use LPU.
