Maybe not. Since nearly all cars are now injected, the refiners have felt free to add various injector cleaner compounds to motor fuel. There was talk in the engine tent about this new hell. This new stuff may go through most esters and epoxies like a knife through butter. Check with your fuel supplier about this stuff in your proposed fuel. It is almost time for aluminum fuel tanks or race car fuel cells.

Then I scraped off as much of the sticky goo as I could and put the samples in a fresh solution of both varieties.  After that initial surface contamination was cleaned, no more showed up. 

Clearly, ethanol was a culprit.  Whether or not it is the only culprit, I cannot say.  Also, there was something about the original surface of the cured resin that was different from the underlying cured resin.  The thickness of the residue was very small.  If you are going to use the OMP (which I do) beware of ethanol.
