The stuff you're looking for is called pro-seal check out aircraft
spruce part # 09-38560 The maintenance shop at your local airport can
likely sell you the little bit you'll need but check the expiry date
the stuff has a shelf life of only about 9 months. Also be careful to
get the mix ratio correct .

I have inspection hatches on the sides of my diesel tanks. Currently they
have a rubber (might not actually be rubber) gasket sealing them, but one is
seeping slightly. I'm pretty sure if I tighten the bolts any more they will
shear. I think I need a stikaflex type sealant, but I can't find suitable
for use with diesel fuel... any suggestions, available in the UK preferably

thanks
