FWIW, a yard which performs a significant amount of refurbishment and
rebuilding of Downeast boats uses Brightside, almost exclusively. They use
Awlgrip 545 Primer religiously for all Brightside applications. There is
probably a reason for this. Usually, their sanding ends with 220 grit.

Thanks all for your help on the Boot Top.
Today I mixed some (perhaps 1:7) Penetrol with the Boot Top and got amazing
results. Maybe just maybe better with a little less Penetrol. It wetted out
fine on both the primed and the Sterling surface, did not sag, lost its
bubbles by itself and has a great reflection. Not perfect because of the
'high quality' brush I bought special for the job. Likely a foam brush would
have better results. Anyway, I have to sand the area I first painted that
failed, and so will sand all with 220 and do it over again for a finish
coat. After I got the hang of handling this paint (quite different than
normal Brightside) some parts look like spray finish.
