I just came across this product from 3M. It is suppose to be a glue/adhesive for Polyproplene and other HARD to bond plastics. The product is 3M ScotchWeld DP-8005.Here is a link to a newsletter from 3M about this product. Hope this helps someone out.http://www.3m.com/profile/pressbox/scotchweldpackrel.htmlPS: I have no idea if this stuff works!
