So what are these things made of anyway?

I was talking with my friends last night regarding some of the repairs I need to do on my car (rock chip, hit and run) and they came to about 700 bucks worth of damage.

When I got an estimate, I was told that my hood is fiberglass. I know the bumper is the urethane plastic stuff. When I said that a friend of mine said that the doors and trunklid are glass as well. We did a "knock test" and sure enough the hood and doors have a similar clunk thats way different from the fender and 1/4 panel clunk.

So I figured I'd come here to get it all straight. Are the doors/hood/whatever else fiberglass?

Thanks in advance.
 
Yeah.. I was under the impression that the only non-metal body panels were the front and rear bumpers, which are polyurethane. I'm fairly sure if your doors, quarterpanels, etc were made out of fiberglass they wouldn't give when hit by a door or in little fender betters. Ever seen a fiberglass bodykit in an accident? The stuff is so brittle that it doesn't give at all, just cracks. Of course, I could be dead wrong.
 
The hood isn't your typical fiberglass. Its a bunch of nondirectional glass fibers blended with a lot of plastic. Of course, that doesn't seem to make it any lighter, and if you've ever drilled into one, you know the dust makes you itch like glass does.
The composition makes it easier to cast parts with creases and grooves like the 99+ hoods.
 
Ford calls the material the hood and trunk lid are made of ,"composite"

The door skins are die-stamped , cold-rolled steel panels. I "pranged" one from the inside - it's pretty easy to do - so I would guess it's 18-20 gauge.

The rocker panels are plastic - a hubcap came rolling at me from across the street while I was doing about 45 mph , and gashed the plastic.

The bumpers are urethane , but too easy to scratch, IMHO. Someone on the board located a place that sells painted ones for $ 185 or so.

With all the plastic, I'm amazed these cars weigh 3200-3300 pounds...
 
Thanks for that post Tripleblack.

After some jacka** stole the wing of my 03. I was looking into getting a Cobra wing placed on. Anyways, when i was talking to different dealerships, etc. I was told that the rear trunk is plastic, and So was the hood. A friend of mine who has an 02 GT also told me that. It is nice to hear that it is "composite" Fiberglass, sounds a hell of a lot better than saying plastic! Does anyone know for sure? :shrug:

take a fridge magnet, go outside and check

or you can simply knock on your hood, then knock on your fender. and have a listen
