Default Cracked Carbon Fiber Hood. Any tips on preventing more or making it less noticeable?

Hey Guys,

I got a seibon cw hood for my 2011 sti and had small crack on it about a year ago. The crack has now grown twice as big and was curious if there was any way to help prevent or slow it from cracking anymore? Any recommendations on maintaining condition on hood as well as preventing it from fading? (which has not occurred yet)

Thanks for reading!

Hood pins will help dissipate the load the hood is seeing at the latch. Also, that's most likely just a 'crack' in the clear. You could have it recleared after you install hood pins.

Fix the crack, then color match it.

I wanted to stay away from hood pins but i dont think there should be any pressure or load on the hood because i removed both dampers (if that was what you were referring to). I had an older post where i had problems with my hood poping up from the pressure of dampers, but i now have them removed and using a prop rod. But your saying i can have my hood recleared? like a clear coat of some sort? Will this hide all the cracks? or only prevent from further cracks?

put the stock hood back on... carbon fibers are no longer the hotness... especially when the stock hood is so light to being with

If it gets to the point where its really bad ill probably end up just getting it painted and leaving the carbon fiber accents on the vents. Which was what i originally wanted to do but didnt want to pay an extra $250...

Stock hood is steel on the 08+ WRX/STi's. Not exactly "light".

Odds are your hood does not have a clear coat on it, but rather a gel coat. You will need to sand out the cracks, then feather back extremely far so there is not a visible low spot. Then clear the entire hood.

The pressure comes when you are moving. The latch is holding the hood down and the hood is flexing. All composite hoods should have hood pin for safety reasons. You run the risk of the hood blowing up while you are driving. Not good for you or others.

FYI: this is what Seibon's website says about their hoods.

"Are hood pins required?
Yes. Although most of our hoods come with built-in latches (depending on whether or not your stock hood has built-in latches), hood pins are required for your own safety."

As far a fading goes the carbon itself won't fade. Depending on what they used for their gelcoat you might (probably not though) get some yellowing. If that happens you can sand the hood and then buff it out and it should look good as new. My experience is not with autobody parts though so.... grain of salt.

I bought a Seibon hood with a crack in the same exact spot. I ran the hood for a while and the crack grew larger. The crack looks almost identical to yours, except of course mine is on 06 model hood. I had hopes it was only in the clear, but I sanded it all the way down to find out it was a crack in the fibers. Ended up reclearing it, and installing hood pins.
I would highly encourage installing hood pins. Watch your hood line near the fenders as you drive, it flexes a ton. The hood scoop is not as large on your model, so may not be as bad.
