Sprayed one coat of dark gray epoxy this morning. There were already a
couple coats of light gray on the car over the bare metal, but I ended up
sanding through to the metal in several places when I was blocking out the
bondo. So, those spots had to get recoated with epoxy for corrosion
protection and proper adhesion of the polyester filling primer that is to soon follow.
I decided on dark gray because... the paint store is closed weekends! I had
just enough light gray in one can and and black in left in another can
to mix together enough to make 1 quart combined. That was enough to
cover the bare spots and to complete one overall thin coat.
But this color will work out pretty well for me. The next coats will be
the Feather Fill G2 polyester 'primer' in the 'Buff' color. When I block sand that this
dark gray base will make it easy to spot the moment that I get close to
breaking through and can go no further.
You can see the numerous spots where the epoxy covered bondo by the dull patches. Some of that is sanding scratches and some of it is because the bondo is porous and sucks up the paint. All sealed and non-porous now though.
