Adhesive for heat insulation??
I am in the final stage of fitting the aluminized matting for heat insulation on the outside of the foot boxes. I will use a thin stainless steel metal border about 1/2" wide around the perimeter however I need some sort of adhesive to keep the main portion of the matting attached to the flat areas of the fiberglass. Is regular 3M or similar spray ok? Or is there somthing more specialized that will not be affected by the heat from the headers.
Thanks Rick |
Rick,
I used the Weldwood that you brush on. I made sure the insulation material was well saturated with glue and allowed to dry. Then I put another coat and let that become tacky and then installed it. In my ERA 10,000 miles later the glue was not affected by the heat. TURK |
Thanks Turk. From Home supply store/hardware store??

Yes,
Also get some reinforced aluminum foil tape from summit. It is about an inch wide and extermely sticky. I used that to hem the edges of the insulation. It cleans it up real good and trims the ends. |
Aluminum foil tape?? I was actually going to have some strips of thin 3/4" wide stainless formed into a "J" to put over the edge and pop rivet but I like the aluminum foil tape idea, had not thought of that. I do not have any seams that need to be overlaped but the edges are of a concern.
Thanks Rick |
Turk:
Any metal borders, pop rivets, mechanical fasteners or just the adhesive by itself? Rick |
Rick-
If you use the Weldwood, make sure you get the Gel type. When I was gluing my carpets in, I first used the Weldwood in the green can and it was horrible. Went on like milk and never did get tackey. Went back to Home Depot and found the Weldwood Gel (red can, but make sure it says Gel, b/c there is another red can that is not the Gel)) and the Gel works great. Roll or brush it on both surfaces, wait 20 minutes for it to get tacky and stick 'em together. Mike |
Rick,
CSX cars come with aluminum bent into a shape to act as retaining moldings. I personally do not like the look of the aluminum riveted in just to keep the heat shield in place. I prefer the cleaner look of the adhesive tape as trim around the edges. I took off the moldings and replaced them with just the shield itself stuck to the foot boxes, and trimmed the edges with the tape. Chaplin is absolutely correct. Spray glue may be OK in an assembly setting, but on or in your car use the kind that does not spray all over the place. If you don't like the over spray from a paint can, you will hate the over spray from a can of glue. |
