There should be no question about applying a protective
coating of some kind on all surfaces that might (will) someday have fluids
spilled on them. Even fixed gear Lancairs have fuel and brake fluids that
can leak and soak into the prepreg. I have been very happy with the
results of using PPG DP50LF epoxy primer mixed about 50/50 with the regular
Jeffco construction epoxy. Huh? I mix the DP50LF/DP401LF per
directions and mix an approximately equal amount of the Jeffco 1307LV/3102 and
then dump the two together and stir. Brush this in place and it gives a
very durable surface. Two coats seem about right. I also use
this as a wheel well coating. Sure makes spill clean up easier.
