How to cement weatherstrip with Al Knoch cement

[Donald H.]

I'm doing my door weatherstrip this weekend on my 60. I did the trunk and deck lids using Weldwood contact cement. For the Weldwood, I brushed cement on both the body surface and the weatherstrip, let it dry to tacky then stuck together. Seem to work very good.

I just got a quart of Al Knoch's cement and it more yellow that the Weldwood which looks tan to me. So I though I would try the Knoch cement on my doors. I used the same technique, coated both surfaces and let it tack dry, but I does not seem to stick very well. So I read the instructions on the can, Knoch's instruction seem to say coat both surfaces and then stick together immediately.

If you have used the Al Knoch cement on your weatherstrip, what application technique did you use, and did it stick good.

By the way, I did pre clean both the weatherstrip and door surfaces with was and grease cleaner before I started.

Thanks,

Don Harris

Don,

I used Weldwood with great success using your method however I incorporated a hair dryer which almost immediately creates a bond between the body and w/s. The hair dryer will take the place of waiting for the glue "tack up". You'll be surprised at the bonding difference. Should work for the Al Knoch brand as well.

I was happy with the Weldwood but was trying the Knoch since it has a more yellow tone. But was not real happy with it's adhesion, at least for the weatherstrip

I bought iit primarily to do the carpet

I recently used some of the AL Knoch adhesive that I bought to use with the new carpet set for my 64. I used it to attach the rubber weather strip on the rear of the hood on my 66. I coated both surfaces, let it tack-up and pressed the surfaces together. Where there were curves I used small plastic clamps to hold the surfaces together. Seemed to work just fine.

I believe the carpet cement is spray on and the W/s is in a tube. You will have better results with the Weldwood for W/S. The color is closer to what was used originally

The carpet glue I got from Al Knoch is the brush on type in a one quart metal paint can.

Same here, Al Knoch is quart can brush on type. It is actually made for Knoch by DAP Weldwood, says so on the can. However, it is more yellow than the hardware store Weldwood contact cement. And if the can instructions are correct, you brush on both surfaces then stick together immediately. Say on the can that if you wait more than 10 minutes, you have to re-coat.

WARNING! The vapors from the glue are very Flammable. I was gluing the carpet in the rear of my 1966 Coupe. I tried to make the carpet a little more pliable with some heat, I was working by myself, when the vapors erupted in a ball of flame. The gas tank is located directly under the rear compartment. I lost most of the hair off my right arm. Please be careful with the glue vapors.
