How do you freshen up the rear fender on an R100GS?

How do you clean/freshen up the black rear fender on an '89 R100GS?

Whip New available online or at Wal-Mart and other fine retailers.

If it is raw plastic (i.e. unpainted) peanut butter works wonders. Just work it like a wax. Make sure you use creamy as the crunchy is too hard to work with.
I used this method on the oxidized turn signal housings of my K100RS 13,000 miles ago and they still look great.

My son found this stuff at AutoZone. I see that it is sold by two different manufacturers.

It is called "Ultimate Black" and is designed especially for black plastics. This is the McGuire brand. His was Mother's brand I think. I liked his better. But, boy, I am telling you, that it takes and makes all black plastic, rubber (fork boots, tires, handlebar controls, etc.) look like new. Very easy to use, and better than anything I have ever seen. Also, it is not meant to make most black plastic shiny

Do not confuse this with such products as tire black or tire sheen. That stuff leaves a coating and a mess on plastic.

I thought I had heard most everything about BMW maintenance but peanut butter is a brand new one for me. I don't doubt for a minute that it works - vegetable oils can do some interesting things, and the smashed peanut meat is probably a mild abrasive.

I wonder if peanut oil would work just as well?

And, I don't suppose it needs to be made from German peanuts, does it?

"Vell, der ver zwei peanuts, valking down der Strasse, und von vas . . . assaulted peanut."

edit - an old Monty Phyton schtick.

Bacon grease will do wonders, however, watch out for stray dogs! Mayonaisse will also work.

Now we have a use for Kentucky Fried Chicken leftovers!!

I wonder if I go around town to the KFC's and collect up all their garbage, maybe I can package it for sale at the various BMW shops. There just would have to be a statement on the package like, "use before 9/30/13"

Bacon grease ... mayonaisse...peanut butter......


The problem is this.. after parking your bike somewhere, when you come back out, you have to fight a pack of dogs just to get to it!

No telling what you might attract at Yosemite.

And they said BMW's weren't popular!
