plastic is pouris. there for the gas kinda penetrates thru the plastic tank. take a look at most tecate tanks, they are discolored a light brownish color after time because of this reason. as the gas penetrates thru the plastic it eats the glue on the back of the decals and ruins them, making them bubble and fall off. same for paint. without lining your take, with redcote, or the lining stuff from caswell, the paint will eventually just fall off. i coated my tank with redcote, had the tank professionally painted, slapped on the decals and the thing still looks the same today as it did the day i got it back from my uncle who painted it. because of the recote!!! line the tank, its not hard to do. and redcotes not expensive either. all depends on you and what you want.

Life's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways, totally worn out, shouting "HOLY SH-T, what a ride!"
