I am in the process of reviving a car that has sat for several years.=20
The gas tank was partially full of old gas, which when pumped out=20
brought out a lot of rust. As such, I am thinking I will be needing to=20
clean out and restore the inside of this tank.

Do any of you have experience with any of the gas tank restoration kits=20
on the market? If so, please share your experience of using it and how=20
it performed over time.

I'm sure others will offer other opinions, such as 'just use muriatic=20
acid', 'just use vinegar', 'just use Coca-Cola', etc... - So, I'll bite:=20
If you have actually used something other than a commercial kit, please=20
share those experiences, too!

Thanks in advance.
