We use this stuff on aircraft at Lockheed.(interior trim etc...NOT, I repeat NOT to glue the landing gear back on. I don`t care what you heard, I wasn`t there that day, that`s my story and I`m sticking to it.) Seriously though, the stuff works great, and you should be able to find it at good auto parts and/or industrial supply stores. If you do use it, apply to both the hood and to the pad, and then let it tack up good (several minutes) before installing. Then CAREFULLY put the pad on, making sure to keep it properly aligned. Once it`s on, it`s on. Good luck Chris L.

It is not that hard; just remove as much of the old stuff as possible, as follows: 1. Cover your engine with a cloth or something; the old foam will crumble and is messy to clean up. 2. Use a shop vac to vacuum off as much of the old foam as possible. It comes off surprisingly easily with a shop vacuum. 3. Use a plastic putty knife to scrape off any residue. Don't worry about any excess glue. 4. Should you decide to use OEM hood foam from 928 Specialists or one of the other vendors, be careful when installing it. The replacement foam is a "peel and stick" application...you need to align the foam carefully and peel of the backing slowly...if you peel off the entire backing at once you run the risk of premature contact with the hood and won't be able to remove it without damaging it.
