Stirring the epoxy according to the directions is critical.It’s worthwhile to consider just how versatile epoxy primer is when
working with vehicle parts. It is all but impossible to sand the inside of
some areas, but with epoxy, it’s no problem. Clean it, primer it and color
it, and it’s done. Sanding is not necessary between the primer and color,
which really helps on oddly shaped pieces. However, if epoxy is applied
before body filler, then the epoxy does need to be sanded. Make sure the
primer is fully dried (24 hours) before applying body filler.
If epoxy primer is applied and allowed to fully dry, then it needs to be
sanded lightly before applying a top coat. This ensures a good
mechanical adhesion between the primer and the top coat. Epoxy primer
can also be used as a sealer by adding extra urethane-grade reducer (up
to three parts). This makes the primer much thinner so it can go on
smoother.
Once the priming and sanding is completed and all the repeated steps
with body filler and blocking are complete, an application of sealer over
the whole job gives the paint a better surface to bite to. After the spray
work is done with the epoxy, it cleans up with lacquer thinner or
urethane-grade reducer. Don’t wait too long to clean up the paint gun,
