One that section of the hood pad is on and secure, apply glue onto the hood pad and the under side of the hood and massage the hood into place.
At this point you will see low spots, here you will need to pull down the hood pad and apply more glue.
The trick is to constantly move your hands all over the hood pad to make sure that the glue adheres.
Here is the finished job.
My under hood was fairly clean, which meant that not a lot of effort was required and hence the complete job took no longer then 45 minutes.
I left some flat cardboard boxes under the hood of the car to keep the pad in place until the glue dried.
