Color of adhesive for plenum
« on: January 19, 2022, 09:19:39 AM »
What is the appropriate/correct color of the adhesive to attach plenum to 1968 Shelby GT500 KR, car is white?  I read Mr Tim Lea's article where he stated and showed a reddish brown.  My other unrestored 1968 KR is white also and the adhesive is black.  Went to several auction results at Mecum and Barrett to look at pictures of sold cars.  Most appeared to be black adhesive, some were painted the same color as the car.

The reddish orange adhesive was used at the factory

If you have something different please post some photos

Probably "restored" cars. The original color of the goo was ugly orange/brown, unpainted as the plenum was attached after the hood was painted.

After your post I went back out and looked at the unrestored.  I found small places where the adhesive is reddish brown, it looks like someone used a paint brush and painted it black.  Probably wanting to cover up the ugly original color.

Not only is it ugly but they let it ooze out like the attack of the blob, BUT THAT IS ORIGINAL. I suppose trimming it back was never part of the installation plan or charge?

Was that the only adhesive suitable for bonding fiberglass back in 1968? If black was available, probably they would have used?

It was an AOSmith product used by them to bond together their proprietary fiberglass reinforced plastic

Usually when you use a high contrast color like that it has a purpose. You just want to verify that the adhesive is applied which fits in to them letting it ooze out.

Does it change color when cured?
