Ya can call and sell a rose by any other name but Phenol novalac epoxy is the only thing worth repairing it with, if applied well and thick enough.
Caswell sealer:
Hardest most chemically resistant epoxy known to mankind, I just lined a brand new 5 gallon fiberglass cafe racer tank with it.

I concur with Caswell's for fiberglass. Clean the tank well, abrade the inside by shaking the tank vigorously with a handful of 1" drywall screws. This system has worked well on three of my fiberglass tanks and I use it in metal tanks, too. Rusty and pin-holed, no problem. Just prep it well.

I caswell-treated my FG tank several years ago and it looks as clean/good internally as it did when new. No issues re fuel at all.

Comnoz and hand full of others have failed to coat steel or fiber tanks in the past with novalac 2 part resin, so might consider heating fiber tank a while, like a day, to hopefully cook off solvents and then acetone wash/rinse and more cooking off prior to actual coating. Don't think of the coating as thick paint layer process but a re-making of inner tank, thick enough to point could dissolve all the original yet still have intact tank remaining and cook or leave in hot sun some too before boozing it up on the road.

Count the screws before amd after abrading.

Re: anyone experienced this product with his fiberglass tank

I researched this novalac topic quite a bit. There are many formulations of novolac EPOXY at least a dozen.
Some resisted ethynol....some resisted petroleum AKA gasoline, but I have YET and continue to look for the blend/manufacturer that does BOTH.
FWIW there is a family of novalac POLYESTER resin that I will try for my replica Dunstall tanks and norton fastback and interstate tanks.
The novalc resin tanks will get a final layer of the novalac EPOXY prior to bonding the halves together.
