I've heard mixed things about XXX man, some seem to come out great, some come out shocking, its really annoying as obviously i am not too keen on spending 3-4 grand on a kit when the car itself is probably only worth that much, and its just for appearence, but again i don't want to pay a cent towards anything thats going to look ****. I was going to buy a mondaro style bonnet from him as well, i've heard great things, and the end results speak for themselves.
Buy the bonnet from Savage Fibreglass as I linked to. Its a bonnet.. it needs to be strong, and you will be seeing both sides of the panel, so you need it to look good on both sides.
The XXX stuff is too weak, soon as you drop the bonnet it will smash, and if its needs fixing, will be much harder to fix since you need both sides to look good.
The XXX kit was crap but only $650 its a good deal in the end if you are willing to do the work.
If you are expecting it to bolt on, fit well and not fall apart, I say steer clear of them. When I bought the kit, the guy told me that if I drove the car to Melbourne and paid $600 bucks extra, he would make the kit especially for the job so it could be fitted 'before it sets too hard, its more pliable and I can get a perfect fit that way.'
When I came to collect the car, parts of the kit were 15mm out... he said to me thats normal, once its painted you wont even notice it... took me out the back to show cars he had done and painted.. all were bad fits, and he said 'see you cant even notice'. I said you gotta be joking, this is half an inch too long here, fits badly there etc... then he tried to say 'obviously the car has been in an accident'. Not true, I have the full history of this car from the day it was made, every receipt, every service, the lot. Accident damage is easy to find, there is none, and of course is he saying that every finished car he showed me had also had accidents?
I hit a roo on the way home, obviously not his fault, but it showed me that underneath the gelcoat was completely dry fibreglass mat.. no resin!!!!!!!!!
If you dont mind doing the work, the cheap kit is a good option. If you cant or wont work with fibreglass, I would stay as far away as possible from XXX.
