Finally got my tank all sealed, coated, painted, leak-tested and ready to go back in the truck. I'll have a write up on it soon.

I don't want to prematurely declare victory, but it's looking good so far. All told, I have roughly $100 into reconditioning this thing. It's all stuff any half-competent home mechanic can do. The worst part is constantly picking up the tank to slosh and drain everything. Your arms will get a workout
