I recently bought the gas tank kit from Classic Industries. It's a galvanized tank. I noticed some people painted it to the underbody color, or clear-coated it. What do you recommend? I'be been told that if I don't put something on it rust will appear even if it's galvanized. Any thoughts?

clear coat it....jmho

most that are 'painted' , I think have undercoating on them....

Eastwood's makes a coating that "looks" galvanised called Tank Tone. That's what I used. A heavy clear coat (Eastwood's offers those, too) would be another good choice.

If your tank is new then clear coat it. The tank tone is good too, but I would just clear it and be done.

Clear is a little touchy with surface adhesion on bare metal. The tank tone would probably stick better. I used POR 15 silver on mine and it worked good.

I finally opened the box that the fuel tank came in. It's already coated with a light silverish-gray coating. I don't think I'm going to mess with it because it looks nice.

my new tank is the same way.i like how it looks. im going to put it in without doing anything to it. tony

Man, I'd still clear coat them.

Classic now has Stainless tanks also. Seen them when I was there this week. I put mine in and didn't coat it.

Here are a couple of pictures of my tank. I shot it with tank tone. I didnt sand it down so you will see imperfections on the top, but no one sees that side anyways
Looks good for an original tank:

Joe,
That color is close to what my new tank color is. I noticed on the side of the box it says the tank is galvanized, and painted with a special coating for durability. It looks really nice. The funny thing is I will probably end up putting a fuel injectin system on my car (after bodywork/paint, 455, etc., etc.). I will have to replace the tank again at that point with a tank that is baffled with an in tank fuel pump.
