Worked on the gas tank after going to Northern Tool and picking up, sand, goggles, and a 3m P100 respirator. The neighborhood had Darth Vader sand blasting a gas tank in the back yard. The tank is cleaning up good. It's hard to rust through 8th inch steel. The Kreem sealer showed up in pints. I thought I was buying quarts and now I am concerned about coverage, so I might have to drop another $50. I will wait to coat it went it warms up a bit.
Also calculated volume of the tank that I engineered 23 years ago, and it shows to be about a 20 gallon tank. That's a perfect size!
