So, at a request, here's a short writeup.
WEAR GLOVES and clothes you DON'T care about! DO NOT SCREW WITH THIS STUFF! My arms itched for 3 days, and I got some in my shoes, which I threw away.
I used Fiberglass Resin and THICK fiberglass to begin with.

*Rough up your fairing (both front and back) with some 400 grit sanding paper, then clean it fully and keep it dry.
*Cut some of the THIN fiberglass material first, (I forget what it's called) to about a 1/2 inch larger than the shape of the gaping hole.
*Apply the resin mixed with the hardener to the fiberglass piece while it sits on a piece of trashbag or plastic, as well as the area around the hole. Don't forget the hardener or life will suck. :goofy: Also, the resin dries FAST - about 120 seconds, so don't take any phone calls while you're working.
*Apply the piece to the back of the fairing first. I think I used 2 layers, maybe 3.
*Once that hardens, then switch to the THICK STUFF, but cut it to about 1/8 in larger than the hole. I don't remember how many of these it took to build up, but I must've used about 5 on each side as a minimum.
*Wet these with resin/hardener and build onto the front side of the fairing.
*Once it's dried (maybe 20 minutes?) and you've got it built up to where you want it - even with the plastic - you can build with a little resin and no fiberglass if you like, or just leave it to the bondo.
*We enjoy air tools, so our best grinding was done with a 300, 200 and 100 grit sanding disc set. THIS SHIZ GOES EVERYWHERE, YOU MUST WEAR A BREATHER MASK AND GOGGLES!!!!!
*Here you may want to use Bondo with the LONG FIBERS, or if you've built up your fiberglass well enough, just use some finishing glaze. Remember; how you sand that layer of glaze is how your paint will turn out. Work your way up from 200/400/600/1000/1500. If you're using sandable primer like I did in the next step, then you can stop at 1000. I won't go into painting, but I'll say that this wasn't that hard to do!!
WHILE WAITING IN BETWEEN COATS, I ALWAYS RECOMMEND A GOOD SESSION OF FEEDING THINGS INTO THE SHREDDER AND WATCHING THE BEWILDERED CAT.
When repainting, I used this paint process:
2 Coats Pink
3 Coats Clear
4 Coats Huyabusa Red (Shh, don't tell!)
4 Coats Clear.
Baby came out great as you can see! The turn signals are Lockhart Phillips I think, can't remember. About 30$?
