After some research I followed Marks suggestions and bought a can of Red-kote for the tank. I did the minimum amount of prep work since I just cleaned and rebuilt the whole saw, blocked the fuel line port and used a can of brake cleaner.
Let me just tell/warn you guys my little craft corner quickly became a Sh¡t Show of epic proportions with the tank sealer.
I made a funnel out of a paper plate and then attempted to pour the sealer straight from the can , this did not work so well! It literally ran down the side and all over the place then I poured too much into the tank and got more sealer on my gloves! Now I had a real mess going on , down in the carb box all over my bench and gloves! So I had wrapped the gas cap in a sandwich bag for swirling the sealer around and put it in place . I quickly" tried" to get as much sealer off the new paint job and handle as possible, but it cures and sticks and becomes long sticky strands of madness!
Anyway its cured and I didn't screw up too much of the paint. Forewarned!
I've got two saws pending a tank coating, so thanks for the heads up! Note to self: do not do above...
