I'm working on the fuel tank for the Fiat and it has a few tiny pin holes in it. Is there any type of sealant or patching compound I can/should use to fix it?

I once had a '70 Fiat 124 Sport Spyder with a leak in the bottom of its' gas tank (not that that makes me specially qualified to answer this).
As I recall, it was at a crease that was caused by the tank bottoming-out on something - maybe a speed bump. Anyway, I priced a new tank which was approx. $120 at the time ~1977 and I didn't feel rich enough to pay that, so on some advice I tried PC-7 - just drained the tank, cleaned the spot down to bare metal and applied the stuff, let it dry a day, and that held strong until the cars' final demise 4-5 years later.

Don't know about Fiats but I once had a 1950's Ferguson tractor [wish I still did] that developed pin hole leaks in the fuel tank. I used an old plumbers trick of soldering 1 cent coins over each hole and there were still no leaks when I sold it 6 years later. Unfortunately you can't do this in Oz any more because we no longer have 1 cent coins.

The Eastwood company makes a gas tank sealer. I've never tried it so I don't know how well it works.
