I have read about that tip before, and I've tried it once when I tried removing some dried polish from the exterior trim of the CR-V. However, I eventually used some APC and a brush, as the peanut butter tip apparently didn't work for me.

If your aim is to "maintain" your car's rubber, vinyl, and plastic trim, then I would agree with the others.

IMO it's better to regularly use a protectant for your car's exterior trim. Protectants are specifically formulated for those types of surfaces. They also provide some shield to the sun's UV rays, which I guess is one of the worst enemies of exterior trim.

Hope this helps.
