Yes,if you have already cut it,its a problem.I worked with all kinds of plastics and there are some,like polyethylene and polypropylene that just do not stick to glue.(assuming you are correct about it being polypro)
You might try searching for HiTec Specialties.They make a nice lightweight foam core epoxy glass kevlar sort of stock,and there os McMillan,Bell and Carlson,etc.
If you run over a cat it does not help to back up and run over it again.It just gets flatter.
