I've never heard of the peanut butter one, I got a purdy good laugh of imagining me out there in the driveway with peanut butter and a butterknife spreading it all over the doorhandles

I always just used some tire shine to get the wax off.

 

I used 303 this weekend to get the wax off the black trim. Its supposed to rain tomorrow so we'll see how it holds up.

 

Military boot dressing!
A black leather dye that isn't wax, doesn't fade and is cheap and easy to apply.
I had my truck detailed after I bought it and saw this guy whip out a bottle of the stuff. He had custom cut the sponge aplicator to a triangle to get into corners. Works on rub rails, bumpers, mirrors, and handles. On real old cars it will recolor the weatherstripping too.
