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.
