How-To: Install Front Weatherstripping on CF Hood

I was asked about this in the Reverse Cowl hood GB thread, so Tyrant and I did it on his car today, should work on any CF hood that has a factory-like liner.

( The disclaimer: I in no way warrant this how-to. When drilling into your hood you are an your own. If you use the tape and are careful, you should be OK. But don't blame me if something awful happens.)


First-off, tools you'll need:
drill
11/64" drill bit, if you can't find that size 3/16" will do.
masking tape
utility knife or Xacto

You'll also need the weatherstripping, part no. B30D-56-770A, should cost around $20.

1. Open the package and take out the strip. It'll have a bunch of plastic pins in it, (see below) take them out.

2. There will be a hole in the round part at the center, find it, you'll reference that when putting it on the car.

3. Now take some tape, and wrap it around the drill bit, leaving about 1/4" of the tip exposed. The best way to do this is to stick one end of the tape to the drill bit and spin the drill, and let it do the winding. Make sure it's a pretty big hunk of tape, THIS IS WHAT KEEPS YOU FROM DRILLING THROUGH THE HOOD!

4. Now tape the weatherstripping to the car, starting in the center. Use your stock hood to see how close to get it to the front edge and use the hole in the strip to line it up with the center of the hood latch. Throw the ends over the hood to keep it from falling off until you get enough tape on it.

When you're done taping, it should look like this:

Don't worry if it sags a little, as long as it was taped right to begin with.

5. Now you're ready to drill the first hole. Start in the center. Mark the hole by gently starting to drill with the weatherstrip in place.

Now pull back the weatherstrip to find your mark and drill the hole.

6. OK, at the three center holes, the fibreglass is thicker for the hood latch. To make up for this, you must trim the two little "ears" shorter on the plastic pins. This is so they will grab on the inside of the fibreglass. If they're too long, the pin won't grab and will fall out.
In the first picture, the "ear" on the right has been shortened, and in the second they both have. They don't have to be exact.

7. Now push the pin in. Hopefully, you'll hear a little click, and when you tug on it, it won't come out. If not, go back and trim the ears a little shorter, but not too short, or else they won't grab inside the hole. Repeat this for the other two center holes. You do not have to trim the pins for the other holes, just the three in the center

8. Now do the same mark, drill, and push in the pin for the rest of the holes.

When you come to these areas,

Be especially careful to smush the stripping around the curves, so it fits like stock.

9. Put the last pin in, end take the tape off and admire your work.

Damn, and I didn't even post the really bad one. Curse of having strong nails, and a general laziness, hehe.
 
wrench i had to test this on the drive home, before the passenger side started to lift when i hit 60mph, now it doesnt look like its lifting at all, just some flutter in the middle of the hood.

but then agian the hood held up doing 110mph before the weather striping.
 
Oh, why the weatherstripping? Theoretically, it helps keep air from getting under the hood causing it to lift. Seems to have worked well on Tyrant's car. He was getting some significant lift on one side that has now stopped, according to him. Trying to not have to use hoodpins. Also, helps keep dirt from getting in there.
