No, vulcanizing was a process for making natural rubber more durable by the addition of sulfur. I don't think that modern synthetic elastomers even go thru a vulcanizing process anymore. Bonding rubber to metal may involve some special pretreatment of the metal; I'm not so sure about that in general. I've made polyurethane parts which were bonded to alum, and for this process we had to paint the alum with a special bonding agent first. For the work that I did, I just used products made by Devcon for their Flexane line of castable polyurethanes. The data sheets for many of the superglues specifically mention bonding rubber to metal, although it's quite likely that there are problems with certain combinations or conditions under which this doesn't work well, or doesn't last long. The few times I've used it to repair something it has worked fine, however. I've used super glue to repair those little metal/rubber/metal sandwich bumpers that sit on each side of a squareback rear door. The ones I repaired never came apart again. They're not under much load, however. > Part Number I have is 311301265D I'll have to check that tonight. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
