Avgas proofing glass fibre

How does one fuel proof GRP ?
I have a painted cowl ( 2pack ) but a fuel drip from the carb ( perfectly normal for this type) is staining the inside and I assume will eventually attack the glassfibre structure. Is there a recommended coating ?
thanks
David

Most epoxy resins once fully cured are unaffected by petrol. My entire tank is made of epoxy/glass layups.

There are several tank proofing products available to seal and protect the inside of any tank. I guess a coat of that should stop/reduce staining.

My tank is Carbon Fiber and is fine.
