Not sure exactly what it’s for and the description on Eastwood.com is a little ambiguous:
“Fill grinding marks, scratches and pinholes with this finishing and blending catalyzed polyester glaze. Extra thin to spread smoothly. Formulated with ZNX-7tm to promote superior adhesion to galvanized steel, aluminum, bare steel SMC and paint. 30 fl. oz. pump container w/ blue cream hardener.”
Is this a metal filler like Lab Metal? Is it for bare metal, primered,? Is it a primer?
PS- what is shelf life? ‘Cause I don’t even remember buying it.
