I need some info on repairing leaks in fiberglass fuel
tanks.I'm hoping for a non invasive procedure, something
like the metal tank guys do with low viscosity sealants
applied to the outside & a light vacuum applied to the tank
to pull sealant into the leak.

Have any of you 'glass airframe guys had any experience with
this?

If you can help, please email me offline at:

I think that is of intense interest to all of us building composite airplanes.
Pin hole leaks in composite airplane fuel tanks appears to be a very
common problem.

One of the guys, maybe John, had a guy fill the tank with freon at low pressure and use an airconditioning leak sniffer to at least nail down the source of the leaks. The molecules are much smaller so I guess they will make it easier.
