Kirby, it may be due to the current gasoline formulas, but I've heard many reports of Kreem failures in the last few years. Kaswell's phenol novolac epoxy kit is reported to be very good. It appears to be the same type of phenolic epoxy that's used to line industrial chemical tanks.
Thanks for that Jim.
The guy that recommended it to me told me that it has to be done right and its not easy and you have to take your time and do it right.
I personally (not saying it does not happen) have never heard of a failure but then people don't usually keep machines for a very long period.
I did a tank about 18 months ago and it is still good. I did coat a steel container (gas can) with the left over product and covered it in a gal of gas. (reg) and it is still like new.
I have no interest in promoting this product, just throwing something out there that I have direct experience with for someone that asked.
