I will do my best to de-hodge it !
So nobody has any experience ( successful anyway ) with a solvent ( Acetone, MEK etc. ) of any kind that will remove the gas tank coating inside.. based on my question in the "help" section. So I was basically provided a couple of recommendations: a) have a radiator shop "burn it out" and re-coat it ... or option b) shit-can the tank and find something else.
so.. being poor, I went with option c : I put some gas in it ,gave it a swish , drained and repeated. Then I filled it with gas yesterday.... checked later this afternoon and nothing drips gas, it seems fine and if MEK and Acetone can't remove tank coating, I'm sure gasoline will be just fine in it.
