What color /type of paint do you use on the gas tank to get a similar look of the original finish? I don`t think it is in good enough shape to just clear coat. BTW, this tank is not available new or NOS anywhere. I have some Eastwoods tank tone and the color is off and it seems to scratch easy. Does anyone refinish/recoat gas tanks?

That looks fine to me. If I wanted to refinish it I'd use ZRC Cold Galvanizing Compound. I suspect, but don't know, when new, the tanks were formed from electro galvanized sheet metal.

When I judge Mopars I take points off if it has a new tank, they are made wrong and look wrong. Nothing better than an original tank with original finish on it. Just clean it up the best you can and leave it alone. twocents

I`ll see what it looks like when I get the rest of the paint off. The other side of the tank is not as nice. The pic shows the top of the tank.

Memory isn't what it used to be.
But I believe tanks were Nitrine (sp ck ) plated

If you have to paint it Import Magnesium Engine Paint works pretty well and close the original color and sheen of the factory finish.

Metal gas tanks before 2012 were made of terne sheet, which is basically solder coated steel sheet. At the steel mill, the steel sheet was hot dipped in terne alloy, 10-20% tin and the remainder lead.

Nowadays terne sheet is steel sheet coated with all tin, no lead. This might look slightly different from the old kind with lead, but not much. The most obvious appearance difference in old and new tanks is new tanks are shiny and old tanks are dull from age, just as old solder or old lead turns dull from atmospheric corrosion. When cars from the muscle era were new, their tanks were shiny, just like new solder is shiny.

If counting off for new tanks just because they are shiny, I would reconsider, because when the old tanks were new, they were shiny also. In other words, what might be considered an "original" finish on an old tank is not original at all - it's a different finish from original because it has aged and turned dull.

Solder is usually roughly half tin, half lead, but repairs to old tanks can be made with solder.

You are correct.

As of a couple years ago you could still source Terne out of Japan. The lead time is at least 6 months and you need to buy a lot.

There is no paint that I know of that will look like it.
