Subject: | Re: Pinhole leak in top of tank. |
Six or seven years since I re-Kreemed my fiberglas tanks, and they're
still going strong without leaks or any other problems...and that's
almost 1200 flying hours.

Subject: | Pinhole leak in top of tank. |
Thanks for the help guys. I'll be re- sloshing with thinned Kreem, and also
hitting the area with epoxy, and also applying a thin sheet of aluminum and
Proseal over the area. The last one was suggested and I didn't think it
would look very nice, but I'll have to patch over the area anyway so it
might be an idea.
