Well today was an interesting day.

I completed painting a small fabric patch on the right wing in prep for mounting the wings to the fuselage.

These are 2005 vintage wings/tanks built under the builder assist program at SkyStar, covered and painted with Aerothane.

We decided to slosh the right tank for possible release agents and contamination. Mixed a 50/50 solution of acetone and avgas. While sloshing we had a significant leak at the finger strainer fittings. The solution wetted the fabric along the leading edge in the tank bay and some of the lower rib lines, before we could get it cleaned up some of the paint blistered.

Several questions:

Does anyone have a recommended sealant for the fittings, as I'm not too impressed with the Permatex used by Skystar.

These tanks don't have the sump quick drain fittings. Can/should they be added?

The slosh solution damaged the paint (soaked thru from the back side), but I doesn't seem too have much effect on the polytac/polybrush/fabric bonds. Is this a problem?

Thanks in advance for any feedback you can give.
