Gas tank sealer

[BDurgin1@aol.com]

I've heard there are a number of different products recommended for sealing
fuel tanks.  I'm getting ready to drop mine next week from it's origianl spot
for the last 35 years for a number of  other reasons, but I'm not sure it
leaks or at least doesn't seem to at this point.  Nonetheless, I want to seal
it up before putting it back in....

1.  Opinions on which internal sealer is best?

2.      Do I need to use a special seal or paint on the exterior prior to
refitting?

Thanks,
