forgot to update. Its pretty well fixed, for now.
Sanded quickfair with 80/100 grit
rolled on a few coats of System Three highbuild epoxy primer. Started with 2 coats over the patch, then two more working out. Sand primer with 220
rolled and tipped first coat of sterling paint. Not really concerned with runs or sags at this paint, just trying to get some coverage.
Let first coat set up over night, sanded sags/lines out with 320 grit. Rolled and tipped a second coat.
It is not 100% though, I now have a bout 4 coats on the repair area and it shows that my coverage on the rest of the hull is thin (if you look hard at it). The repair area looks better that the rest of the side. So now, I have to put one continuous coat on the whole port side
that might have to wait until I get a new motor though.
