If you will ONLY use 100LL, then it may be okay. But if you are planning to use autogas, then the strong solvent properties of autogas may well attack the sloshing compound, and the crumbling compound may block fuel flow. That happened to the RV builder. It was a nightmare to get the flaking stuff out of the tank. Sealing from outside: When I was faced with leak problems, I simply sealed ALL seams from the outside. That solved the problem for a while. Then I decided to have all tanks remade by a reliable company. Their welding was first rate, and since then there have been no leaks whatsoever. Good luck, and happy flying, Klaus ________________________________ Message 2 _____________________________________ Time: 06:00:16 AM PST US From: "n801bh@netzero.com" Subject: Re: Zenith-List: Re: SEALING A FUEL TANK Properly applied and using the correct product sloshing compound will wo rk great.

I have a Pitts and I removed the tank ( about 10 yrs ago ) to slosh since it was weeping at one of the welds. The sloshing compound was the best you could buy. It started to flake off and I spent many hours removing the tank boiling it out with paint removers, MEK, and soap and water.

Sloshing a tank that has had fu el in it for any extended period of time will usually lead to poor adhe sion of the sloshing compound. It is VERY hard to properly prep the tank without either removing it from the wing, load some sharp edged gravel or removing the whole wing and getting some strong guys to shake. flip a nd shake some more to abrade the inner tank surface. Doing that along wi th multiple flushings with MEK will prep the tank to let the compound to grip the the surface. Just sloshing the tank without removing the exist ing fuel varnish thats stuck in the inner surface is asking for trouble.

McMaster-Carr sells all sorts and I bought the 60 pound model which worked very well for me. Their model number with description is: 9416K123 GAS SPRING WITH THREADED ENDS, 60 FORCE, 8.15" EXTENDED LENGTH, 3.54" STROKE Price was $11.15 each in March of this year.
