I have a crack in my rear fender. Whats the best way to repair this? Would two ton epoxy hold. Its a 900 classic and the crack is in the wheel well edge.
I wouldn't waste your time with epoxy. It's not flexible and will never stick. It has to be plastic welded with an actual plastic welder. That's the only way to repair abs plastic.Thanks for the replies. Here was my plan. I found some epoxy specifically made for abs plastic. So I am going to scuff up each side of the crack and epoxy it, as well as sand the inside of the fender then slap some gorilla tape over the crack on the inside. If it doesn't hold I found a fender on ebay for $125.
Plastic Weld epoxy would work fine if the surfaces were prepared properly and the epoxy is mixed properly. It's not as good as actual plastic welding obviously, but depending on where the crack is and how bad it is would determine if ultra flexibility is required. If epoxy is used I would suggest reinforcing the back with fiberglass instead of the "gorilla tape" tho. I still stand behind my initial comment that plastic welding is the best option for repair, second to complete replacement, with epoxy and fiberglass reinforcement being the 3rd choice.I wouldn't waste your time with epoxy.

Lets us know how it holds up over time/miles. It could be one more thing in the tool kit.Ok just wanted to give everyone an update and cheap fix if this happens to them. I ended up going to Home Depot and getting Oatey ABS cement (may have to order it depending on building codes in your area).
Now for the steps I used.
Clean the fender with soap and water then dry
Clean both sides of the crack and backside of fender with acetate.
Apply ABS cement to both sides of the crack
Apply cement over crack on backside of the fender.
Clean any excess cement up with a acetate damped shop towel.
Let it set
Now she's good as new.
