The alluminum hood on EVO VIII is light but it sure does dent and chip easily. Is anyone else having the same problem?

Aluminum IS easily dentable.
Which is also why you should never let any of those car show ****** lean on your car for pics! :P

Please don't mention any chips. I got one from a salt laying on the road and is like 1cm big, only good thing about that it happen right on the egde and chipped just the layer not the whole paint. But I'm pissed anyway.

I had a car kick up a small twig from a tree in front of me at about 40 mph and it dented my hood.... it bugs.

I have a nice ding on the hood and trunk lid. I've had an estimate done and I cdn almost buy a CF hood and trunk likd for that much.

Speaking of Aluminum hoods and their upgrades, I got to wondering about the dent-resistance of carbon fiber hoods. I think "dentability" is basically indicated by a material's Modulus of Elasticity. So I did a little digging on www.matweb.com, and found that the average modulus of elasticity for aluminum tends to be between 60Gpa-70Gpa, usually upper 60's. Most of the branded CF (continuous type) composites I found have modulus of elasticity well over 250Gpa (some were upwards of 400Gpa). (I'm sure it's not news that CF is more dent-resistant than Al alloy, just putting some firm numbers with it).
Anybody know what type of alloy Mitsubishi uses for their body panels?

Carbon Fiber does not dent, it cracks in the same way that fiberglass cracks. After all, it's resin penetrated fabric.Originally posted by evo8282

real CF won't crack... only cheap made ones with a fiberglass base.. real cf you can jump on and it will flex.........Originally posted by JohnnyChimpo

No, real CF will crack as well...what do you think it is? Kryptonite? All materials can fail given enough stress and pressure. And what do you mean by "fiberglass base"? Do you mean fiberglass mesh that's laid up to look carbon fiber?Originally posted by Grod101

no what he means is that some companies specifically for the aftermarket ricer crowd, use a fiberglass base then lay carbon fiber with resin over it to cut costs. Some companies use dry carbon fiber some use the cheap wet carbon fiber. While the dry is lighter, more durable, and more expensive. The wet carbon fiber can be viewed as brittle under the same abuse a dry carbon fiber piece would withstand. CF is made to crack, but wet carbon fiber cracks a lot easier compared to dry carbon fiber. As you said, anything will crack under enough pressure, but some crappy carbon fiber products out there give misconceptions about ALL carbon fiber products.Originally posted by JohnnyChimpo
