Gas tanks paint and heat shield

[crossram]

Is there a good reason to paint the gas tanks?

If so what type of paint do you like?

Powder paint? will the heat affect the stuff inside the tanks?

Is it necessary to put some type of heat shield on the tanks? If so what did you use?

The paint is to prevent corrosion on the bare ali. Most of the tanks surface you will never see again and the tank cannot be removed.

I doubt the foam inside will like the heat of powder coating. Pretty much any paint will do the job but you must start with an etch primer.

On mine I covered the top and inboard faces with the glass fibre and ali foil heat matt which stays looking good for many years.

Agree with everything Steve has said.

Also remember that the glue doesn't like a fuel leak if you get one......

but if you spill gas doesn't the sticky back come off?

The builder of my car didn't. Looks good as new after 4 years, no corrosion. The tanks are made of very high quality metal as expected from the factory product. Plus with ceramic headers no heat protection is required. Thought of protecting with gold heat protection tape, but after a spirited drive on the hottest day last year, and no issues, have not done anything. It may be different if you drive at 110% all the time in a hot, wet humid and salty environment.

When I rebuilt my car it needed new tanks due to corrosion on the bottom of the tank (12 years old mind!). The builder had used expanding open cell foam to fill the void under and around the tank. Not a good idea. It holds moisture and ally corrodes quickly in that environment.

I am thinking of a "stick on" heat barrier, cold fuel burns better. I am in a hot area that sees temps 32-38 Celsius quite often.

Back in the day Sunoco used a fueling rig that was packed with dry Ice to keep the fuel cool , here it is back at Laguna Seca CA. for a Trans Am race

"Stick-on" material should be sufficient. Check out stuff made by Thermo-Tec or DEI. It seems that DEI offers stuff which is cheaper than Thermo-Tec. Gold sheeting is nice but bloody expensive IMO

This is the stuff I used, which is the same I used to paint the inside of the body panels, doors etc.
