View Full Version : Protecting Your New Gas Tank + The Carter Twist

I think I came up with the following key preservation steps. This is even more important to me as we run in salt water. Anyway, here goes..........corrections welcome!

1. Scotchguard the entire surface of the aluminum tank and remove EVERY BIT OF SHINE on that aluminum.

2. Clean the entire gas tank surface with a mild soap like Dawn, then dry it with a towel and hair dryer.

3. Wipe down the entire tank with Acetone to remove any traces of oil or contaminants.

4. Now prime the bare gas tank with 3 coats of BASF R-MEP789 two part epoxy primer in black. This particular primer has a lot of zinc chromate. Second choice would be Interlux Primocon.

5. Next and final step will be to apply George Carter's coal tar epoxy treatment.
....I think this is the stuff...."Epoxy.com Product #216 Coal Tar Epoxy Coating Resin System" is a two component coal tar epoxy coating used to protect steel,
....concrete structures, timber, and other construction materials in corrosive environments. In certain applications, only apply to the bottom, sides, and ends of the custom tank.

The above 5 steps are all intended to protect the tank but as important is how you then properly install the tank. Good Luck.

Greg, by George, You've got it!:)

If Donzi had done ANYTHING at all in the old days, we wouldn't be having these issues.
One other thing, replace the old drain under the tank w/a new (I increase the size to 1" PVC)
drain pipe that is epoxied in at both ends. The old connections is where most of the water
comes from.

That sounds like it'll do the job.... for a long time!

What about using Line-X / Rhino liner type truck bed liner as a coating? (presumably after steps 1-4) I've run into a couple of people that say this is the ticket and it provides more than prevention of oxidation.

For added clarity, I presume you are talking about aluminum tanks, yes? (Not sure it's even possible to have a steel tank built anymore, but...)

Yes Mike.
I think only aluminum (or aluminium if you're a Brit or Canadian) or HDPE are the only materials permissible.

I've been asked this before. It sounds good. All our pickups are lined and it holds up well, particularly when you consider we deliver salt.

Bit of a different animal as they're not belly tanks... but I had this tank made out of stainless steel (and powder coated). They would make anything I wanted.

Oh, fwiw we say "Aluminum" not, "Al-u-minium" like the Brits... and maybe the Aussies... :)

I've found that making a tight blanket of beaver pelts works just as good..Ed

Well, it also worked for the "Courier de Bois". :) (But, they weren't Irish)

Sean, your rules are a bit different than our CG rules. The last time I checked, we could have SST tanks
up to 10 US gallons. They're tubular like your picture, but w/dish ends. In other words, only two structural
welds. But who needs a 10 gallon tank?

The idea of substituting Rhino for Coal Tar is appealing if it does the same thing woobs. Less work and less mess.

I had Rhino in the box of my pick up for 10 years and the tail gate still looked like new..Ed
