I had this product installed on my bike last Saturday by the owner of the company here in Escondido California.

His name is Lucas and if you call the phone number on the web site he usually is the one answering the phone.
He is selling a kit that for the GTR1400, which he used my bike to model his kit...
There are two different materials that he sells for our bikes. Tank slapper material which is less permanent and 3M tape which is more permanent and durable.
I had 3M installed on the front and sides of the front fender, the top of the tank, the top and fronts of the saddle bags and the fronts of the mirrors. I had the tank slapper material applied to the knees areas, headlights and front fairing around the headlights.
All of the material used is clear and once installed you cannot see it. You can feel edges but that's it. I am very pleased with this extra little bit of insurance on the bike to resist scrapes and scratches.
The cost in US dollars was $90 including installation. The installation did not appear to be easy. You have to have patience and watch his installation video from his site before you install yourself.
I highly recommend this product. If you call him mention "Steve and the '08 Concourse14". I am in no way associated nor do I profit from his product/business but the stuff works and is invisible!
I used lite skinz precut once found them great, probably same 3M stuff.

I just bought a Magknight tank protector. It is color matched to the 2008 silver Concours. When I get it, I'll post some pictures. I have one on my zx14 and it works great. It is kind of expensive at $116 shipped but it beats repainting a gas tank. Here's a link,
