I've used great planes, Fuel can fittings for my nitro gas. I checked for leaks, and when I tip over the bottle it leaks a bit. I've already tried puttying a little seran wrap around the fittings to stop the leaking, and it didn't work.

Would it be okay for me to put glue around the fittings, on the surface of the fuel bottle cap? Since I can just re use the cap, when I buy a new jug of fuel.
