Peanut butter, seriously. There is a thread somewhere on here. I remember laughing and then I had to try it. It gets the wax off and makes your fenders nice and luxy. Plus all the neighborhood dogs will love your E.
clean it off with peanut butter, then give the E a nice wash
usually, i tape around the plastic before i got ahead and detail my E, wax it, then spray some armor all protectant on the plastic, and it shines real good, and won't attract as much dirt as tire shine, or peanut butter
A guy around the corner from details cars. I asked him about that and he showed me a special brush, looked like a tooth brush but was made of horse hair. He said good like finding one, but I haven't really searched.
