As I said , I am about 99% sure I found the best thing for motorcycle seats, and other leather/plastic items you want to shine, but don't want slippery..
http://HTTP://WWW.JUSTONCE.COMI bought this stuff from the advice of a friend, mainly for my sprayed in Line-X bedliner in my truck.
I read on the bottle as it said it leaves a "protected" non-slip surface, due to the lack of silicone.
I sprayed my bed and it does work , as it looks like brand new, went on easy , etc..

So I got curious and wiped the excess off the rag onto my CB seat, and it made the thing look 10 times better, and it
wasn't slippery

I made the mistake once on my first bike of lube-in up the seat, and my balls paid the price the first stop I made

They say it is safe for motorcycle tires as well - but I don't know if I wanna trust my life to what is printed on a bottle, but I did the sidewalls and it does look good.
Just thought I would throw this out their for other people to try. I am in no way associated with this product or the manf, just a fellow CB'er trying to help out the fellow enthusiast...
