Some folks also like to remove the hood and lay it across a couple of saw horses or on the grass. Takes the overspray out of the equation and also lets the hood pad lay in place and not want to peel off......

I've heard that this stuff can be hard to remove but I don't plan on changing the pad a second time, lol. I've done 3 or 4 this way so far. No worries about overspray, either. Only hassle is you need to press the new pad into the adhesive beads by hand, all over, and this takes more effort than you might think. But you can re-position the pad if necessary. The 3M Super spray will probably stick on contact, the downside being you have little if any time to re-position the pad if you didn't get it located perfectly.

:stuart:

You can always remove the Liquid Nails with a belt sander or wire wheel and then re-primer the hood if you need to replace the pad at a later date. The pads do eventually rot away.

... or just use more Liquid Nails right over top of the old stuff. I'm sure it will hold.:)

When using the 3M 08090, you need to make reference marks on the hood for the center of the top and bottom edges. Then you fold the pad in half (with the adhesive side out), match the marks, then open it up and press it into place. I used a 6" paint roller to burnish the pad to the hood. A full size roller was too easy to bend with the pressure needed to get a good bond.

thanks for all the input. I was thinking of using the 77 because I have a can of it. Just didn't know how well it handles heat. That's a good idea with the PL400 (liquid nails). I have plenty o' tubes of that from work. That stuff will hold anything, as long as it's dry and clean. thanks again!

So is there a good product that removes very old glue? I don't want to sand the hood to remove this old crusty stuff!

I just did mine since it was falling off. I layed a sheet across the engine and took off the old pieces with a spatula and wire wheel on a drill. then painted the surface with regular contact cement like you get from Home Depot for laminate. I then cut to fit a windshield folding sunscreen to match and taped it with silver A/C tape, very sticky and nice looking. it came out nice and looks great.

WHAT?
I am not following what you used the sunscreen for...
or the silver tape...
got pics or a more descriptive explanation?

It sounds like he used the sunscreen for the hood pad??? :eek:
I'm betting glue for wood laminate isn't real heat resistant....... ;)
At least he did something, which is better than I've done on the 2 of mine that don't have a pad.

There are glue removal products -- 3M has one -- but they also remove paint. :eek: This is not so much an appearance item (it will be covered by the new pad) but rather a rust issue. By removing paint, you are exposing the bare metal of the hood underside.

I used a variety of spatulas, metal and plastic, and scraped off as much old glue as I could. Then I cleaned the hood with 409 and water, rinsed well, let it dry. A new layer of 8090 went on hood and pad and with the wife's help, the pad went on easily with the hood in its vertical position. I used the small wooden rollers that are used for wallpaper trim -- you can apply plenty of pressure to bond the pad to the hood.

spray adhesive works just fine
