Makes sense. Aviation is all about certification and reliability, racing is performance above all else, and you’ll always find some old industrial machine in the back of a shop that has somehow been running since longer than anyone remembers.
Reminds me of how despite RoHS and all that, leaded solder is still a thing for some applications like (legacy) aviation and repairs (leaded and unleaded solder apparently don’t mix well, or rather, make things corrode or something like that)
Some have replaced lead.
Aviation gasoline (avgas) for piston aircraft still contains lead.
Certain racing fuels (off-road, track-only) may contain lead.
Some specialty or legacy industrial uses…

I think they call that a galvanic response. Sometimes it’s favorable. Otherwise your support is galvanizing the other. Bad news.
