on my 08 gl the red is turning gold and silver in spots from sun exposure always garaged except when riding. the paint is still shines like it should but the red pigment in the paint is changing when i was into body and paint with autos it was common on some colors of red to change with pigment loss. i looked at one at a honda dealer saturday with the same issue.
I've seen several red bikes (mainly 06 and up 1800's) with paint fade. I just upgraded from a 94 Candy Spectra red to a 10 Caliente Red myself, the paint on the 2010 is in great shape since it only has 3K miles on it. My 94 has little to no paint fade, but for the last 13 years I kept it waxed with Cycle Care Formula 3 wax/polish. With the 2010, I'm switching gears, nothing against Cycle Care, it's a great product, but I don't see it at rallies anymore, so you have to purchase online. I already keep Turtle Wax Ice on the shelf for my car and truck, so I'm just going to use it on the bike as well. I've been pleased with the performance of the Ice on both vehicles, and in a recent of GWRRA's Wing World Magazine, they did an article on waxes and polishes. Turtle Wax Ice claims UV protection and prevents paint fade. I'll use the paste wax a couple of times a year and they have an Ice spray detailer that I can use between washes. One nice thing about the Ice is that it leaves no white residue, so I even wax the black plastic mirrors on the truck.
Clean the paint with Isopropyl Alcohol to remove any old waxes. Buy some automotive Ceramic Coating and apply as directed. It brings the depth and colour out in the paint making the bike look great. I have applied a coating to my bike and trailer myself and they look great. Here is a video I found online explaining what they are.
