[Farmall] Paint blisters on "H" gas tank

[Robert L. Holtzer]

Depends -- the eBay tank may not be any better than what you have.

Doing your own rebuild can be frustrating but it can also be 
rewarding.  You could easily do the temporary repair you 
suggest.  Question is what caused the problem in the first 
place.  After the parade do a more comprehensive repair.

Have fun.
