Tank sealant

[Rodd]

I was watching musclecar a couple weeks ago and they showed how to coat the inside of your tank with a sealant. Has anyone heard of this or tried it. I know our tanks tend to flake and was thinking something like this would be great if it worked. Then I thought how would it work w/ the baffle in there. Any thoughts?

Here's one. I don't have any experience with it though. It's common to need the tank sealed on old tractors.

I think that is the same stuff I saw on MC. I watched the videos on the website and it showed how to do it yourself. Fairly simple but time consuming process. The guy did mention baffles in the tank but some tanks have them built in while others like ours are loose. I wonder how it would work w/ our plastic baffles?

Rodd,

I saw that too on muscle car. In the old days, the tank sealants pretty much sucked. They would soften in the presence of alcohol. (had to pull the heads on my father-in-laws 37 LaSalle as the gummy residue had stuck the valves.....) I think I would certainly ask about the chemical compatibility. I think today there are epoxies and such that can work. Diesel fuel doesn't get exposed to as much alcohol as gassers do. I have had to repair MANY gas vehicle lately due to the uncontrolled amount of alcohol. (I know its so good for the environment.... but no one is counting the countless fuel pumps, and carb rebuild kits and .... in the equation. Sorry I digress)

I think I would buy a new tank if it can be had for less than $250 (most of our trucks can). I think I would consider it only for a restoration of an unobtainable tank, but again I am biased because I have been bitten by inferior tank sealant attempts from the old days.

HTH,
