Just a heads-up: Since that spray-on stuff is kinda messy, I'm guessin yer gonna want to take the fenders off to coat them. The 5 bolts that held my Tglide fender on were VERY!!! tight and I used two breaker bars. Had to grind the bolts heads off two of them cuz I couldn't fit an impact wrench inside the fender well. You might want to get new bolts as they come coated with lock-tite. They were then torqued to spec and have held fine for the last 5 years.
