I used windshield urethane on mine.
Bad idea
Hoods,deck lids ,roofs and doors need something that stays soft yet still being able to stay bonded and be able to expand and contract in varying temperatures without causing ripples,waves and dimples in outer skin.
Do not use seam sealer or windshield urethane if you want your body panels to stay straight especially after months of sweat and blood in body & paint.
Do you have a suggestion? Must look stock. I know the bond material they use on the AMD hoods is soft and spongey - nothing like the original.
I would use anti-flutter two-part foam ,but I'm not a numbers matching,correct overspray,factory markings type,so there is not much I can suggest. The factory stuff gets rock hard and falls out most of the time,that is why I would never use anything similar.
Guys, Just so you know (this is from the LORD website directly), the anti flutter foam is used for:
"LORD FusorŪ 121/124 flexible foam can be used for sound deadening, sealing and filling of door skins to crash bar, hood panel to supports, trunk panel to supports and gas tank filler area."
Just reading the description leads me to believe that this is not intended to bond a skin(hood,door,trunk,roof etc) to a frame/brace.
The term "bonding" is not used anywhere in this description.
It's a filling, sound deadening, anti-flutter foam material that expands inside of a void(brace etc) up to 10 times it's original size. It is not suppose to warp/distort the outer (skin)panel in the process...
True, it is an anti-flutter, which means it should grab the fluttering area (of the skin) that has come apart from its bond... But... I don't think the intent for this is to be used as a bonding agent...
I agree that windshield urethane is not the answer...
Bonding is one thing, anti-flutter is another...
Ughh.. You don't want it bonded. The outer skin has to be able to flex .This is why anti-flutter foam must be used.It has plenty of adhering properties when applied to clean substrate ,so it won't fall out. There are other names for it,and just about every brand has their version of this product.
