Default Polyurethane glue - how come it says not suitable for polyolyfins?

Hi - i finally found some polyurethene glue - it comes in a mastic tube. How come it says not suitable for polyolyfins (e.g. correx)? I thought this is what you non flashers use .

Good question. I bought "Amazing Goop" for "all plastics" and it seems to hold very well, although it says right on the package "Not for use with polypropelene". Mind you, I don't know what that is.

because of the little holes we poke in it. Its a strictly mechanical bond, then, but, its plenty strong, so long as you poke lots of little holes in it, ergo the woodpecker tool.
You'll find that ca isn't supposed to stick to coro either, but, if prepped right, it will.

Yeah, real worlds results often are slightly at odds with label directions, that's why you've got to experiment to find out what REALLY works. Unless it's dangerous, of course.
