I think the right treatment depends on the state of your specific tank.

What are you planning for the exterior? I was thinking of POR15 followed by undercoating (although I learned you really need to use a primer in between for the undercoating to adhere to the POR15).

I am removing the old finish on the outside, then the Marine Clean and Metal Ready, then followed by the black POR15. Now is seems that people also spray on the black POR15 while it is still tacky so it will adhere...
Still not sure what to do with the interior; I already washed with water and liquid soap, and then rinsed with more water.
Although I had the tank filled with water twice there are still some very strong fuel fumes... I'll use some compressed air later this afternoon and see if it makes a difference.
