Sealing leaking fiberglass fuel tank
I have a Avid Flyer with fiberglass fuel tanks. One of the tanks has developed a small seeping leak. Are there any products such as sealers or sloshing compounds that anyone has successfully used to seal a leak like this? What advice do you have for repairing the tank? The factory formed fiberglass tanks that came with the kit were laid up with polyester resin which isn't resistant to alcohol and although I have been careful testing for alcohol in the fuel some contamination may have occurred.
Any feed back on how to seal the leak will be appreciated.

I used the same vacuum procedure for sealing a leak in the end rib of my Glasair's wet wing fuel tank. Worked well but took a couple of rounds. I used a shop vac. Monitor the tank for signs of collapse while applying the vacuum...it doesnt take much. I measured the vacuum with a manaometer. Good luck!
