Body filler?

[blue05twin]

I read the post about fixing cracks and stuff but what I want todo is fill the two holes where the turnsignals go in the front.  I want to mount GSXR 1000 mirror with the built in turn signal but before I do I need to get those holes filled in.  Any advice greatly appreciated.
Or if anyone can do a good job for a  reasonable price let me know and I'll ship you the upper cowling.

i'm not sure what fairings are made of (i ain't got none), but you dont want to use bondo to fill anything bigger than a gouge/scratch.  never use it to fill holes (in plastic, metal, whatever).  bondo is porous and soaks up moisture and cracks if you use it like that, plus it isn't that structurally sound so it can crack with the rattles, flexing, etc.  
if the fairings are nonflexible hard plastic or fiberglass, you can prob use fiberglass to patch.  if the fairings are plastic-y, you'll probably want to find someone with a "plastic welder" to take care of it for you.

big holes need some sort of internal structure....I have found that in the past some small chicken wire JB welded at the corers works very well and then apply very thin coats of bondo to it and sand each coat smooth and making sure it dries completly before the next layer/coat ...The main problem is that the materia has to be ridgid but also have a great amount of material flexability [this is why they use plastic]

use fiberglass and resin it wont crack and its tuffer than the plastic, easy to work with

Thanks I'll give it a shot. . . I mean how bad can I mess it up anyway

just take your time and make sure you sand it the way you want....What you see/feel after sanding is what the finished product will resemble...

just fill it in with some silicone,    like a woman.
