Fiberglass repair

I just remembered I never posted the other day about the fiberglass repairs I did.

Let's just say my goal was to make it strong, and I achieved it. As for pretty---I believe I could have made it much better if I used a regular filler on the outside. Instead I used Bondo Hair, which I found impossible to shape for my purposes, although with a couple of more layers and massive grinding that could have turned out well too. I used fiberglass cloth for the outside on the tail though, just to see if it will be better...

Anyway, I enjoyed the process, here are some pics:

"A blind man would be happy to see it"

I see in a couple of places you've extended the repair beyond the area you cleaned up with the grinder. Sometimes this can lead to problems if the repair doesn't take to the paint. I'll usually grind a generous area around the repair to allow plenty of working space. Once it's finished I'll give the back side a quick shot of paint.

Hahaha :) It's on the right side of the bike, so at most tracks and configurations spectators won't even have to look at it ;)

It seems to have bonded well to the tremclad paint, although not stress-tested yet. But yes--next time I'll grind off the paint for the whole working area. Practice makes better.
 
I have tiny hairline cracks in my front nose fairing. How much approximately would it be to stop crack and paint from your experience?
Personally, I would leave it. But if you insist, send me a picture and I'll show it to my guy.
