I sloshed the safe-T-poxy resin composite tanks on my or with the Bill Hirsch slosh compound sold by Aircraft Spruce. I ran mogas in it for 24 years and never had any issues. A very thin coating is sufficient. There is no reason for thick coatings. You will also hear horror stories about slosh

One KR builder/ friend, used a sloshing compound in his KR fuel tank, and I got to feel it's weight. I can tell you I think it weighed more than my Kr wing with an antenna, fuel tank vent hose, and pitot / static hoses installed. It appeared to be 3/16 inch thick at the fuel cap opening. Do you wan

Hi Sid. I built my fuel tank with vinylester also. My plane got water in the tank( Gas cap seal broke )during a 5 day move from Montana to Ohio. After emptying the 100 low lead from the tank, I used auto gas from a can for my mower, to rinse out any remaining water. In drying the inside of the tank

I have had good luck with the KBS product on metal and fiberglass fuel tanks on ground vehicles. I am SUPER nervous of doing any of them on untested surfaces! If the tank is used and not factory fresh - there is no telling what kind of contaminate and surface conditions you might be trying to a

The problems won;t happen immediately. The alcohol has a tendency of playing havoc with fiberglass (seams were delaminating). I had to do major repairs to my varieze fuel tanks because I put in 100LL with alcohol. My suggestion is that there are gas stations that 100LL does not have alcohol. In NY

N133RM has the original RR fiberglass fuel tank installed in 1993. Roy placarded the tank as "100LL ONLY". I don't know how it was used before I got it. For over 2 years and 130 hours I've used 100LL and recently a mixture of 90% 100LL & 10% Alcohol-free premium gas. No problems here... John Bou

Cured Vinyl ester resin is advertised to be ethanol proof. However, ethanol with 6-percent water is a solvent for cured Vinyl ester resin. Ethanol is hydroscopic; In vented aircraft fuel tanks the ethanol contained in most automotive fuels will draw water vapor from the air at the top of the t
