John, look no further than a member of our site. The best adhesive for PE that I've used is Gator Glue, developed and sold by Ken Loup. Here's a link to his website:
GatorsMask.com It's an adhesive that grips as you set the PE down, gives you time to set (and re-set, in my case

) and dries clear. Takes paint well, too.
You'll probably hear a few more recommendations for it, both here and other sites - it's that good.
Cheers,
Mike
