Fuel tank sealer - any experieces?

[my427cobra]

Hi all. I was wondering what experiences you all may have had with fuel tanks sealers.

I am looking at this from a different perspective.

I have done some mods to the inside of my intake manifold using an aluminum filled refractory putty. Stuck like crazy, hard but ground /shaped well, good to 1000 deg and impervious to gas and oil etc.

I was wondering if it would be a good idea to coat the inside surfaces of the manifold with a sealer like Red Kote or POR15 etc.

I once read that one of Smokey Yunnick's tricks (which Nascar banned to this day) was to coat the inside of the intake manifold to increase flow. He claimed it was slipperier than porting/polishing and easier.

Any thoughts?

Once used the sealer you pour into the tank on one of my Harleys.I cleaned the tanks several times 100% sure they were dry.After 5 or 6 tankfuls of fuel through them one day the bike died.Looking inside saw nothing out of the ordinary,once home with better light saw that the hardened sealer peeled off and layed on top of the fuel spigot.FYI my experience with trying to seal cheap aftermarket tanks.
