As the title suggests, I am not using for door or window weatherstripping (yet). I'm using it as a stop rail (catch rail) mounted atop my electronics workbench to prevent items from rolling off. This M-D strip is absolutely perfect for this application! That said, there's some info in this review that conventional users may also find useful. Its hollow core, combined with EPDM's flexibility/softness also allows me to rest my forearms on the bench while working and remain comfortable doing so. The height of this item (it's actually 9/32" or 7mm) is just right to catch small to medium size items. I don't know why other people are having problems with the adhesive on this product, but I guess it must be due either to temperature extremes over a long period of time and/or the numerous compression cycles pushing on the adhesive tape (shear stress), weakening the bond over time. The adhesive grabs quite well to the Wilsonart white laminate on my bench top. I can tug on the weatherstrip with a fair amount of effort and the tape doesn't budge. My tests show the heat resistance of this material is excellent. The EPDM had no trouble dealing with a molten solder blob dropped directly on it from about 1/2" above. The solder landed and stayed on it till it cooled. It did not melt into the material. I also laid a 700°F soldering iron tip (Weller conical) on this strip. The heat turned it a light brown, but did not melt through it -- the discoloration was mostly cured with Simple Green cleaner. At around 10 seconds the EPDM begins to soften (depression forms). It did not melt through to the hollow core. This material would hold up very well against accidental touching/raking/dropping of a soldering iron (or woodburning iron or glue gun) on it, since that type of incident is likely to be of much shorter duration than 10 seconds. This item is also surprisingly resistant to cutting (e.g., by utility blades). The hollow core, combined with EPDM's softness/flexibility allows the blade to simply "pull" the material rather than immediately slicing through it. It can be cut, of course, but I find this requires either a long blade with one long stroke, or multiple strokes, or a fair amount of downward pressure with or w/o stroke. IOW, one must pretty much intend to cut it or be very careless, as an accidental dropping of a blade won't do much immediate damage, unless the knife is really heavy and hits it just right. The same holds for sharp points (scribers, probe tips, etc.), although I find this material less resistant to poking than to cutting (with a single blade; scissors go through it like butter, of course). I haven't tested it for stain resistance (such as coffee), but I did discover it's resistant to alcohol, acetone, surfactant cleaners, and solvent (styrene, butyrate, abs, acrylic). This item would make an excellent stop rail for a model builder's bench, too. Potential buyers should realize that the total length specified for this -- as with most similar weatherstripping products -- is for the two halves combined. IOW, if you leave the two halves molded together, the length is half what the package states -- you have to rip them apart then put them end to end in order to get the specified total length. Just wanted to alert those who didn't know this. Amazon's price on this item right now is dirt cheap compared to the local hardware stores! Edit 5/20/11: well it WAS dirt cheap when I posted this review. They've since jacked the price up another 5 bucks!
