I didnt think it looked that bad, I was going to go at it with MetalRescue and not even seal it. On the other hand when I got to the dealer he showed me a ton of flaking rust that fell out when he drained the gas. I was surprised.
I think if you bathed this in metal rescue you could get 3-5 years out of it without the rust coming back but what do I know. I dont think its anywhere close to rusting out though.
