Due to an absolutely crazy mistake, i have a big hole in my bumper.
Its an OE pug part made from plastic.
How would i repair such a hole? Will Fiberglass be OK?
Whats all this about 'Plastic weld' i hear about? How is this done??
cheers

I take it that was a guess? 
You should never use fibreglass on plastics. 9 out of 10 busted plastic bumpers which enter bodyshops go in the bin. But if you must fix it, then you should go down the road of plastic welding which a good bodyshop will be able to do, then then instead of using filler to smooth out the repair, they will use a flexable glazing putty designed specifically for plastics, which will be less likely to break or crack under the movment of the plastic.
Alternatively other bodyshops will use new materials which are constantly coming out, like plastic weld which comes in glue form.
Do not use fibreglass on plastic, it WILL crack as it will not properly grip to the plastic no matter how well its key'd.

 hopefully my bodyshop knows their stuff with plastic welding! :S
Might be cheaper to pick up a new bumper for the price it'll cost to repair it??
