I've got a couple of small breaks on my RF900 fairings that I'm going to patch. I have sourced a product (plastex (www.plastex.ca)) which looks to be the product to do the job. I've just got a small pack in to start off with as a tester. What I'm looking for is a small handheld grinder similar to an engraver (or is it just an engraver that I'm after??) Like a cordless screwdriver with a stone tip for cleaning out the crack so that it can be mended. Anyone know where to get one?

After inestigating in depth I found that these things are f*cking expensive!!

Anyone got one that I can loan for a little bit, please?

Actually, they're not all expensive - just the name brands like Dremel. Places like Bunnings have other brands that are much cheaper - around $40 for a complete kit.

Where did you get the plastex from?

You could buy a cheap set of the stones for about $10 from Mitre10/Bunnings/Repco etc and use an electric drill - like mine.

I got the Plastex from Canada through a friend. I've got the demonstration CD and it looks good. I'll let you know wheteher it's any good or once I've done the first patch.

Those cheap kits are complete rubbish, The stones are OK but you'd have to use in a drill for any kinda power.

Im repairing my bike fairings atm, if you are doing a complete job (i.e., full paint of the fairing) you might want to try what I did.

Drill a hole at the end of the crack to stop it spreading
Get an angle grinder / file on the crack to make it big.
Drill some small holes along it for the bog/fiberglass resin to key into
fill with bog or resin (depending if you want strength)
Sand
Prime
Paint.

The good thing about the angle grinder, save from being stupidly quick, I found was it weakly melted the plastic together along the crack - enough to hold it while the resin sets.

Fibreglass resin will stick quite well to fibreglass if you rough it back properly & can make a permanent repair.

However it only sticks to plastic weakly. Or maybe that should be weekly.

I bought a cheap dremil from Miter 10 on sunday
mains powered and over 100 assorted bits, stones, mini sanders, tooth grinders
Has a pencil extention and a hanger, so you dont have to hold onto the weight of the motor to do fine work.
$99.00
Good with the little polishing pads for cleaning those places that are so hard to get into with anything other than a dentists drill!
