I'm dyin' here. This is one of the funniest threads I've ever read...
For Steve Brotherton, you can always use almond, cashew, or hazelnut butter. And I think the oils will work as well as the peanut butter without making your neighbors think you've lost your mind as they watch you smear Skippy on your Mercedes' door handles.But just think how nutz they will think you are when you'r putting it in the grille. They might assume that you are trying to "feed" your Mercedes...
If you want to be extra chic, you could always opt for truffle oil...
As for the candle wax on the bolt trick, I've been using paraffin to loosen up window casings and drawers that don't slide smoothly for years, but it never occurred to me that it would work for rusted bolts...
Here's a contribution from me. Using regular old lighter fluid (naptha) will remove stickers, and the sticky residue left behind, as well as remove grease spots from cloth upholstery (when you blot), remove some hard water deposits, and will also loosen rusted nuts and bolts. Also, if you want to strip paint from plastic and fibreglass with out damaging it with a paint stripper, you can use regular oven cleaner to remove the paint without harming the surface. While paint stripper has solvents that will disolve the plastic, and damage the fibreglass, the oven cleaner is just a highly alkaline cleaning substance so it won't cause harm, but will disolve the paint. I've used it for years on everything from motorcycle side covers and helmets to boat hulls.
