Anybody use this process? I am looking to restore my 70 Challenger gas tank. Mostly surface rust. Just want yo be sure when I put it back in the car it function properly. The car has set for over 20 years and not sure, but more than likely it was left with gas in the tank.

Looks like they boil them out and coat them with black stuff? That's not "restored" that's "fixed" (at best).

I had them "renu" a gas tank for a Charger that I owned years ago. Like it has been stated, they line the inside and outside with a black coating. Personally, I found it to be a hassle - if you do ship the tank through UPS, it has to be perfectly cleaned with no gas smell. I won't even explain why I know this...lol.

If you have to keep the tank, maybe they can line just the inside and you can do a correct cosmetic restoration on the exterior? When I had it done, I didn't have a choice. Either coat it all or forget it.

Personally, I would have it hot tanked at an old-school radiator or engine shop first.

I don't know of any company that properly restores gas tanks (with the original galvanized finish, etc.)

You can try Bill @ BMCUDA.COM - give him a call. He's completed an extensive research process on proper galvanizing for Mopars and developed a process to replicate the original galvanizing. The problem with duplicating the original galvanizing: lead was used in the process, in order to get the proper finish. Though, he's been able to use something else that works pretty well.

So if I bought a new tank are the 70-74 Challengers the same? Except for the ECS of course.

70 without ECS - single vent nipple
70 with ECS and 71 - multiple vent nipples at the side
72 may be the same as 71
73-4 have the multiple vent nipples at the front

Buy a new Spectra Premium tank for under $200 and call it a day

FWIW, I had the tank in my '52 Plymouth done by Gas Tank Renu in 1995 and it's still fine. The tank had major rust and holes before they fixed it.

Like said getting it galvanized is the tough part.

If you want the outside galvanized then a repo is the only option I know of. And even the repos are a little different than the originals galvanizing.

Look inside it, is there rust? If so trash it and get a new repo for a E body since they are easy to get a repo for.

I have reused several used original tanks because there was no rust inside. I media blasted the outside to get the rust off and painted it with Eastwood Tank Tone paint. Looks OK IMO. I would recommend a light silver color(like Tank Tone) over black if one was to paint there gas tank. IMO black absorbs more heat from the pavement than a lighter color.

I recently blasted one and painted it, didn't cost me anything as I already had the blaster and the paint.

Rusty outside.

But very clean inside.

Ready for paint.

I used one of the POR 15 tank restoration kits. It worked great.


That's King Weenie to you!

To the best of my knowledge,,,No.

But to be honest I've never dug into it to ck either( my shop client base is more than happy with a repop tank)

Friend of mine has a real Nos 1970 Challenger tank. Next time I see him and see if I can get a few pictures of it

I have a real NOS Duster tank now, I agree, it's not galvanized (like muffler shields, license plate holders, disc brake backing plates, etc.) similar looking but without the blotches of light and dark zinc particles.

I think the material was probably TERNE which was a trade name of a lead - nickel coated material. It's no longer made in the US but there is a mill in Japan that still makes it.
