Let’s be clear. The county didn’t remove 100LL out of “fears” over lead. They used lead as a justification to try to cripple an airport that they seek to close and redevelop into something more profitable.
I was at the event on Saturday. Got my 337s signed off and filled the tanks. I went flying yesterday, and of course the plane flies just like it flies on 100LL.
Regarding the staining, they gave out a little pamphlet detailing how to clean up spills so as to prevent staining. I do think this is an issue that is going to need additional work to minimize. The pamphlet mentions ceramic coatings. I’m not sure how complete the protection is from that, but I’m hopeful that something along those lines will be shown to be effective.
