Bonding Fiberglass scoop to a steel hood

okay,step 1) first off you need to take your hood down to bare metal where you are going to put the scoop. I would recommend taking down the whole hood but its up to you.

2), spray an acid, or etching primer down, this is to help adhesion.

3), Now you can go with a few options, Bondo is okay just use it sparingly. Fiberglass resin will also work. You can even go with a two part epoxey, just make sure it's for automotive applications.

If you go direct to metal you run the risk of getting moisture under your bondo or resin, and thats what makes your scoop popup and crack.

4) If you go with bondo or resin spread it out about 3 to 5 inches past the scoop. This will help strengthen the scoop and it will also help when you when you smooth it out. just remember to keep it on the thin side. Also use a tiny amount more activator so it will dry fully. bondo has a tendency to shrink over time. I would let it sit for a day before you start sanding on it.

5) After you choose what you're going to use, put somthing heavy on your scoop to help sink it down. (phone books, etc)

6) After all that you're ready for primer and paint. Hope this helps.
