After reading this review I had Edison at Wet Winologist East seal my tanks. My experience was terrible.
My plane was returned with parts; broken, missing and installed incorrectly. (seat belt retractor upside down, Bose headset jack snapped in two, wires broken, etc)
After agreeing to store my plane in a hanger, I returned 3 days latter to discover it had been left out in 3 thunderstorms and August FL weather without tie-downs, cockpit cover, securing control services, etc.
After agreeing on a price of $10,000 to include all work including 4 new tank sender gaskets and wing walk, on day of pick up I was asked to pay $700 more for wing walk and $200 more for interior re-install.
It looks to me like they have few assets, the interior reinstall was hired out to someone else, the A&P who signed the work off was out of house too. I stopped by to check on progress several times in the little over a month the plane was in his care, and only once saw anyone there. On that occasion I saw a lone worker running a power sander in a Mooney tank. I tried to ask him a question but he didn't speak any english.
And that 7 year warranty, if he doesn't do the work it good for 4 hours labor and a quart of sealant only.
