painting fuel tank

Thus spake trevtherev ( snipped-for-privacy@nowt.con) unto the assembled multitudes:

If it's exposed on the underside, might well be worth slapping on a couple of thick coats of underseal.

Never heard of anyone painting fuel tanks other than with,as you say,some sort of underseal...Maybe Hammerite first might protect it .

================================================

Bitumastic paint gives a durable finish, not prone to chipping. Pay particular attention to the exposed edges and corners.

Cic.

OK, Underseal it shall be, possibly with a bit of hammerite in the areas where the old one has corroded. I just wanted to know what was normally done. Thanks for all the answers.

What about the inside of the tank? How and with what do you paint it? I have old one that I have not yet have time to inspect, it might have some rust inside.

I'm not keen on underseal. It seems to me that with the passage of time it can lift in some areas allowing corrosion under it, which goes unnoticed. Better to paint it with Hammerite or bitumastic paint.
