My point is:
It will make trying to FIX the finish or renew it more difficult.
Chassis grease is for lubrication of metal parts not wood finish or polish.
But its America folks can do whatever they like.
Personally I have no desire to rub on my face with a SKIN IRRITANT when shooting a rifle.
But then I would not use linseed oil or shellac for wheel bearing grease either.
Though I know of an instance where one of the less brilliant citizens of Sweetgrass County put linseed oil in a 1990s, then new, JD farm tractor as motor oil. It was in the shop in a drum and was for wood coating of course. But it looked like motor oil... The tractor ran for about 3 days feeding hay etc before it gave up and quit guess the LS oil finally got too thick. Cost his boss over $10K IIRC.
