Those are pretty big cracks. They "could" spread a bit esp. if the hood flexes at speed. I would run by a body shop and see if they can mix you up a touch-up bottle of the appropriate clear coat (MUST be the same type of clear used and compatible with CF resin) and fill in the gap with it. Do it slowly, ie. use a little at a time and let it dry for a few days, then do it again to further fill in the crack if that's possible. Once it's filled in, you can have a body shop rub it down for you.
I would use the reflective material over the hottest spots...just behind the two main vents essentially, going all the way back where the hood meets the windshield. I have an exposed (but wrapped) downpipe so I put a bit more along that side of the hood as well.

Some better picture.
Here is a close up view of the underside of the hood. See how thin the CF is? Daylight can be seen through what looks like only one layer of CF.
Another one as seen from the underside latch. You can actually see daylight through the carbon fiber weave.
3/4 View
From Driver's side
I still like the hood but very very disappointed with the quality. Well, at least some of you can benefit from my disappointment.
I might have to have someone add another layer of FG and paint it for strenght.

is it possible that the cracks formed from the hood pins coming in contact with the hood while driving? If so, using an oversized bit might help. So it actually looks like there is only one layer of carbon fiber? If so thats too bad. Even with its shortcomings, I must say taht it still looks badass on your car.After that revue, I would still like to get one...

maybe i will regret it one day, but i have been running mine for 4-5 months without pins and speeds well in excess of 70 and it is still holding. i check the latch for cracks every time i open the hood. seems to be holding just fine. not trying to advocate not using pins if it makes you feel better, but like i said no problems to date. *knock on wood* hopefully i wont be on here in a couple of months with a "my hood flew up cuz i am a dumbass" story.

Hey Poman, does your hotside piping from the M2 large hit the top of the hood? I have the M2 med. and my pipe rubs the stock lining underneath the hood. Did you buy the hood direct from VIS? Was the $595 including shipping?? I'm sooo tempted to buy one, its looks great, especially on a black car. If I do buy one, I will have it painted silverstone silver to match my car. I dont think a CF hood will look that great on my car without paint. Did it come with rainguttters?

The hood didn't come with rain covers.
$595 shipped. However, I would seriously reconsider purchasing one b/c of how thin the CF is.

Pettit sells the exact same design but in fiberglass. They are made locally in West Palm beach. They also cost a little more $$. BUT consider that the CF hoods are not really CF... They are CF cloth mixed with epoxy resin and fiberglass. "real" CF (and I am talking built for lightweight and strength, as in aircraft) would be tons better than the ones on E-bay. Do not get me wrong. I would like that hood design on my car. But I would get Pettit’s and have it painted.

As far as weight... I seriously doubt the CF hood is noticibly lighter than your FD's already light aluminum hood. We are interisted in these aftermarket hoods because of the improvements in airflow out of the engine bay not light weight. And for safety sake..... you proabbly should have hood pins as well with them.
If you are goign to qote me don't take it out of context. If you want to post simply to shop off your lack of knowledge might I suggest "Brians Rice-boy Page".

I will tell you that it would be far easier to drill fiberglass THICKER (no "CF" cloth imbeded, the owner could see through it) to produce a clean hole and prevent his cracking problem.

A true CF hood (and I am talking REAL CF that has to be heated and baked in special high temp molds) would be stronger and lighter than the fiberglass (not to mention much more $$) "look good hoods" that are readibly available for us.
Thank you for the nice website. I had no idea you had family photo's on line.

This will be my last post so it doesn't fog up the original thread. I am just simply stating the differance between the two wouldn't be noticable in a hood anymore than the weight you injest from your lunch. Same goes with strength. I don't understand what was so hard to understand.
I had no idea the website I posted would actually work.

Your generalization is incorrect on both weight and strength and reveals an utter lack of knowlege on CF components.
Weight - a CF hood is about half the weight of comparable structurally comparable FG hood.
Strength - A real CF hood would be one or more order of magnitude times as strong in bending and torsion than a FG hood.
A real CF hood would be several layers of CF with the resin vaccum extruded so that the resin is dispersed evenly though the CF fiber. Thereafter, the CF fiber and resin would be baked in an autoclave at something north of 500F so that the fiber and resin are interlocked such that they're stronger than steel. It's so strong that the Porsche GT, the $550,000 one, has a chassis tub made of just that CF.
The Vis CF KS hood actually feels heavier than the stock hood.
I knew that this wasn't the real **** but I was more interested in moving heat out of the engine bay and a plug and play solution.
However, it looks like what I'll do is cut out the vents and lip portion of this KS hood, cutout a rectangle corresponding to the KS vent on my stock hood, fiberglass the cut out KS vents/lips with the stock hood and paint the whole thing again.
Any one wants to sell me a good condition stock hood in any color for cheap?
One last note: I recall that FuManchu has some sort of business relation to Vis Racing Sports (sponsorship???) in other forum postings. As such, FuManchu words should be taken with a very very large grain of salt.
As a side note, when I ordered the hood through Carbon Creations, at least two different entities took over the processing of the purchase, JTR Import and a company called Karachi. This rang alot of bells in my head b/c as an attorney, this looks like there is a bunch of holding corporations for just a simple hood? Why go through so much efforts?

On a small hood like the FD, those weight differances wouldn't matter at all. I am not arguing for or against CF hoods. I don't get what was so hard to comprehend on my posts. Also, I used to be sponsored by VIS. I still can't figure out why you brought that up in this post. It had nothing to do with anything I said.
