<VV> Gas tank sealing

[chris c]

As the weather turns.  I am ready to clean out the 65's gas tank.  Its 
solid with no leaks.
The filler neck hose was shot.  I was ready to buy my supplies, but 
silly me, reading the instructions before purchase.

 >>>> from the POR-15 website
*SHOULD I ALWAYS USE A FUEL TANK SEALER AFTER THOROUGHLY CLEANING OUT MY 
TANK?
*No. Fuel tank sealer should be used as a last resort, and is not always 
necessary. Fuel tanks that are rust-free and have no pinholes or leaks 
may not need sealing at all. They should, however, always be kept full 
of gasoline, which prevents condensation and further rusting. If 
vehicles are not used frequently, fuel tanks should be treated with 
POR-15 FUEL PRESERVATIVE/STABILIZER, which will keep fuel fresh for more 
than two years and insure quick starts even after months of non-use.

Does this mean its a waste of money to purchase the sealer?  It is out, 
and the tank is from 65.  I have been running the car for 12 years now.  
Cleaned it out in the car several times with it in the car.  Flush with 
water, wipe out with socks on a hanger, repeat.
I fill the tank at the end of the season.  Put it away, and run it a 
couple times over the winter...even took the 63 out this week.
