Oh, I believe Acerbis well knows the effects of what goes into their tanks.......now. I'm certain that Ducati saw to that.
But in their defense, when the nylon tanks were specified, the consequences of U.S. produced ethanol were not in the equation.
The bike mfgrs also were caught flat footed. They wanted plastic tanks they could paint, so went with the nylon, using the current ethanol information which did not put much emphasis on phase separation effects. The longevity of the black plastic tanks were known, but they could not be painted and required additional covers/fairings.
What is interesting is the manner in which the bike mfgrs handle plastic tank warranty claims. I don't know about the rest of the world, but in the U.S. the tank is considered part of the emissions system and comes under the 5 year or 18,641 mile emission control warranty. I have heard of some dealers who repeatedly seem to forget that and will not support their customer without some re-education.
Ditto re all the stripper advice re plastic specific stripper. But emphasized dittos re just sanding down to good paint and avoiding the stripper if possible.
Myself, if I were determined to keep a plastic tank bike, I would do an interior coating before considering a re-paint.
