model. This style tank with the fuel filler on the right side was a later version of the tank used on early pushrod competition cars where the filler was located in the middle of the boot lid. The undercoat did it's job and there was no rust on the exterior of the tank, unfortunately the inside was rusted but there were no perforations. I ended up using a few handfuls of ball bearings which were dropped in the tank and shaken for about an hour which dislodged all of the loose scale. The tank was washed with a detergent, then Muriatic acid, then phosphoric acid, rinsing with water between steps, followed by acetone then a tank sealer. The exterior was bead blasted and painted with an epoxy paint. |
