Can anyone can give me some advice on epoxies that will withstand higher
temps. I have a center mounted top exhaust system (IO-540 heads on a IO-360)
which causes my top cowl surface temps to get up to 250 F. I want to uses a
higher temp fiberglass in this area. I opted to go with S-glass, but I can't
find any info or supplier who supply high temp resins. Would appreciate any
info in this area.
