Application 08/081,744
to an elevated temperature said defects being caused by
emanating subsurface gases, said process comprising:
first heating said molded thermoset fiber reinforced
plastic part, said part having one or more machined surfaces
formed by cutting or abrading, to a temperature of from about
120EF (49EC) to 400EF (204EC),
then applying a coating of a liquid epoxy composition to
one or more the machined surfaces of said part, wherein said
liquid epoxy composition has a Brookfield viscosity at 25EC of
less than 4,000 poise,
and thereafter allowing said liquid epoxy composition to
cure into a thermoset coating,
wherein said liquid epoxy composition comprises at least
one oligomer having two or more reactive epoxy end groups and
a hardener component reactive with said epoxy end groups, and
wherein said defects are paint pops and paint craters in
subsequently applied surface coatings.
