[Spridgets] gas tank sealing

[Mike Rambour]

  So this is not 100% Spridget related but I am putting in a 1098 into 
my car, so it is a Sprite motor and gearbox :)

  I got a "new" gas tank for my car.  Its brand new but was made a 
decade ago and has surface rust all over it, inside and out.  Its really 
light rust, not a concern.  The guy that had these tanks made said some 
had minor leaks and I should check for leaks. Thinking about rigging up 
something to pressure test it with compressed air instead of filling it 
with water as he suggested. The tank inside is pretty rust free, except 
where they welded the bungs for drain plug and filler plug and also the 
baffles, seems the welding area is what rusted on the inside.  Outside 
is just surface rust all over.

  I have used Hirsch tank sealer in the past with more or less success, 
but I see POR and Eastwood and many others are out there now.  Those 
would also seal any pinholes according to them.

  Any recommendations ? I am not against sending it out and having it 
done but I think being brand new and rust being minor, I should be able 
to do this myself.  The tank is fully exposed when in the car so its not 
something I can send out where they coat the inside and outside of the 
tank, only the inside can be done because the outside is painted car 
color and fully visible.  That is the only reason I am considering 
sending it out to have it cleaned of rust and coated inside, I don't 
want to use the wrong product, have to fix it and have to repaint it in 
a few years.
