fiberglassing advice

Ive got some body work to be done on some sharkskinz race work. I have done alot of fiberglassing work but most of my experience is "first time" construction i.e. speaker boxes... not patching old fiberlgass.

What can be done before hand to prep the surface of the old fiberglass and to make sure the new stuff will properly adhere to the surface? dont want my repairs flaking off at 100mph......

Should i drill a few small holes in the old stuff before similiar to the way you do with bondo?

anyone got tips?

no need to drill holes, but sand it down all the way to raw fiberglass out past the damaged area about 2 inches, patch it, then sand smooth again.

sand down to the mat itself? should i sand it enough to slightly fray the mat so the new glass has something to adhere to?

Grind out the cracks. Then tape something smooth (on a small crack maybe like a popsicle stick covered in plastic so the resin don't glue it to your fairing) on the out side and then fill in the gap with fiberglass. Then lay a couple layers over the patch on the inside. Bondo as little as possible.
Reinforce (at least 2 layers) anywhere it seems weak. Bondo as little as possible.
Check out the edges of the openings for smoothness, cracks, or sharp corners. Bondo as little as possible.
Use good quality resin.

Not too hard to do at all. Repairing fiberglass is the easiest thing in the world to do.
Clean all the oil and grime off the inside of the bodywork.
Rough it up (on the inside of the bodywork) with 60 grit.
Put down some resin (after mixed with hardener).
Lay the fiberglass fabric and apply resin on top of it with a paint brush.
Lay 3-4 layers of 'glass using that same method.

If you don't care about the outside, you are done. If you want it to look good, rough up the outside of the bodywork with 60 grit and apply Bond-o. To make it really strong as well as look good, use a Dremel or some rotary tool with large sanding drum to cut a "valley" in the crack and rough the outside of the cracked area with 60 grit, then apply Bond-o type gel coat repair, sand, then Bond-o body filler, sand, then you're done.

Or... you could just drop it off with Tom or Tony. They take excellent care of MHers.

+1 for tom's technique, only never use bondo on fairings... its not flexible, fairings are... crack crack crack!
use the bondo hair or gel its got less filler and will result in a less brittle repair that will last longer.
