Not sure if this is the correct section but...
So, the previous owner of my bike laid it down and damaged a few parts, including the left fairing. Well, going out and replacing the fairing was unfortunately not an option for me, so I figured I would just repair it and paint it. I have searched high and low for instructions on how to repair it, but have only been able to find suggestions with no list of products used. With that being said, here is a step by step of what I did to repair the fairing. Don't mind the image quality, I was working with a camera phone and it was getting late at night.
This is what I was working with...

last one...
I know I know, how could I ride around with it looking that way? First was the trip to Home Depot! These supplies were fairly inexpensive (less than buy a new fairing) so you don't have to worry about breaking the bank to do this.
Time to start with a little ABS Cement (PLEASE WEAR GLOVES)
Depending on the damage that has been done, you may or may not need to do this in sections. As you can see on my fairings, there was quite a bit to repair. You will want to only put a very thin layer down (need it to dry quickly) and hold the pieces firmly together so that it will bond. You want to be sure to keep it as straight as possible or you will end up with an uneven surface to work with when you go to sand. As stated before, you may need to do this is small sections (about 3 or 4 inches at a time) which in my case at least, will make it easier. Also, having a buddy there to help hold it with aide in keeping it straight.
Next you will need to grab some fiberglass mat.
You will want to cut the piece so that you have a least an inch or two on either side of the crack.
Now I found that it is better to not let the original coat dry completely before putting the fiberglass mat down, and also to spread the cement on the corners first.
On to the fun part! I went with epoxy because of how cheap it is and it fills in the holes perfectly.
You will notice that the heat rating on the epoxy is not the highest, but the outside of the fairings really do not really get that hot, and the ABS Cement and fiberglass mat put a nice barrier between the engine and the epoxy.
It's not going to look pretty...
You may end up with air bubbles, or need to apply a second layer of epoxy (like me) so I sanded it down a little bit before applying my second layer
After all that work, you are now ready to begin sanding. I purchased a 3M disk that can be attached to a drill to make it go by quickly. Started with 60 grit, then 100, 200, 400, 1000, and ended with 2000. Now, I kinda rushed this part so there are still a few spots that could use a little more filling, and a few spots that could have been a little more evenly sanded...but I wasn't going for perfection. After painting, you can barely notice it, and you really have to be up close to see.
After final sanding...
NO MORE HOLES!!
The repairs were cheap to do, and the paint wasn't much worst either. I used a can of Krylon which is designed for painting plastic, and there is no prep work needed.
I don't have a picture of the final product, but when I do I will post it. The process took me 2 days, but that is because I ran out of the sandpaper I needed and had to wait to pick some up. If you have any questions, feel free to PM me.
