It's also available in a 10oz cartridge (for a caulking gun).
Call manufacturer's customer service for help. They may have a proprietary adhesive that will work just great. However, having used the silicone sealant you will continue to have severe adhesion problems every place you used it. The general rule is, silicones stick well to other silicones, but nothing else ever does.

I believe you cant use caulks that contain more than about 20% silicone with poly boards.
Thanks for the opinions, I'll use a sample piece and try different sealants to experiment. With other than silicon I'd be afraid of mildew growth. Jesse
