New Thread on Leaking Wing Tanks

[cliffy]

What ever happened to the company that sold leak sealer that was sucked into the leak from the outside by slight vacuum on the the tank?

It looked like red locktight fluid.

Don't know about the red stuff but I've see and done the same thing with Pro-Seal.

Cliffy-

It is called "AeroSeal" and was made by Norm Smith (the Mooney Miser) years ago.  He died, but it looks like his family is keeping it going.

I applied it to my first Mooney back in the late 1990's.  Only now, almost 20 years later, does the current owner finally need a tank re-seal.

I had a friend years ago with an E at my airport that used it and it worked fine for him, too. 

Always thought it was a good option.

Some folks report success using Locktite 420 ( Part#42050 ) as a vacumn assisted penetrate seal  seeping screws or rivits that are part of tank assembly and minor leaks.  I understand that it will keep in the refrigerator for a long time.  Better use a plastic tube water manometer in a U configuration,  maybe taped to the side of a cardboard box to limit vacuum to a few inches of water.  A plasticT  from Ace and a carefully monitored shop vac complete the rig.  Seems like there is one more trick involving a wad of putty.   Watch the vac carefully, too much and you destroy the wing.  Draw and monitor on the tank vent.  Once you get the vac, have a way to pinch the tubing shut as vac should hold pretty well.  If not you probably need new cap O rings or just tape over cap.   Of course tank selector should be to OFF.  A few drops will do.  The difficult part is getting the tank empty and dried out.

Drain the tank out the bottom, and park in the sun with the cap off. Should dry pretty well inside. Of course, this works better on a sunny summer day . . . especially down South!   Or in Texas.
