Re: A question about additives
Not many left today but when we used to use real magnesium rims on our race cars we always sprayed them with WD to keep them shiny. Magnesium will darken and tarnish almost over night but WD kept them pretty for race days.
ATF: Try it as a hand cleaner if your hands are greasy from dirty work. It will usually clean better than most commercial hand cleaners.
When I was into R/C planes I used ATF to protect the engines after a day of flying. Drain the fuel, squirt in a spoonfull of tranny fluid and spin the prop a few times. The engine would never 'gum up' even if not run for weeks or months.
My apologies to the OP. We sort of got off topic but did inject some useful info that others might find useful.
