Bridge cap materials

[gordon stelter]

Thanks!  I thought this was why pre-catalyzed finishes
stayed liquid in the can:that the lacquer thinner kept
the catalytic action from occurring, but once it
evaporates after spraying all's back to normal, and
the chemical reaction proceeds. Are you quite sure????
Can you cite an authoritative source that states that
thinning weakens the finally cured product? In any
event, there are water thin (Epotek 301) epoxies that
should permeate bridge material just fine, even more
so if GENTLY warmed by wafting a heat gun over at high
altitude. AND WEARING A CARBON FILTER MASK!!!!!!
     But over warming WILL weaken the cured product.
This I know, so be cautious.
