Cotton batting always works.
Some quilters here have posted they use polyester batting and spray basting works fine for them; others say it doesn't stick well. It may depend on which basting spray is used and possibly also which brand of polyester batting is used.
I don't remember seeing any posts about 505 not working with polyester batting, so it would probably be the best one to try if you want to use poly.
