I have new plastics on order for my 400f. My old plastics arent cracked, just scratched up quite a bit. I was thinking about whether I should throw them away and then I thought of an idea...At my local auto parts store they sell this truck bed liner spray in multi colors including a blue that is very close to the bikes color. I have expiramented with the stuff before with my running boards on my truck. It works great. It is flexible, sticks really good and doesnt peel, and it is scratch PROOF! I think I will expirament with the old plastics and see if it looks good. If it does, the scratch problem would be solved. Plus, if it gets gouged from a crash, I can touch it up with the spray.
