Maybe where you get you're epoxy it's the consistancy of congealed snot, but
my supplier put enough diluant in his laminating epoxy so that it easily
wets out the glass.

70-90% ISO ALCOHOL WORKS, BUT THE ACETONE, ETC. TYPE SOLVENTS MORE
COMMONLY USED


Since laminating epoxy doesn't contain any VOCs in the first place, why
introduce them when denatured alcohol works just fine and doesn't alter the
finished material?

WORKS TOO BUT EPOXY IS HARDER TO SAND...


Than what, fairing putty?

Why?


BECAUSE HULL IS SUN DAMAGED WEATHERED GLASS. A THIN COAT OF EPOXY MAKES A
FRESH BONDING SURFACE FOR ANY TOPCOAT OF PAINT. ALSO SEALS THE PATCH
SPOTS. ALSO IF SKIP THIS STEP THE PAINT OVER THE PATCHES MAY HAVE A
DIFFERENT LEVEL OF GLOSS


Again, that's why high build primer exists.


AGAIN, NOT FOR BUILD BUT FOR BONDING. EPOXIES ARE GENERALLY THE BEST OF
PRIMERS....


Huh?

Why do you think high build primer exists?


WE ALSO SELL HIGH END COMMERCIAL ENAMELS AND 2 PART LPU POLYS, BUT ON A
PROJECT LIKE THIS HARDWARE STORE ENAMEL IS FINE.


Guess I value my time more than you do.

What ever floats your boat.
