I tried it with a Walmart polyester batt and it did need to dry overnight. The glue held fine, I stitched through it fine except a couple of thick spots did cause the needle to shift a bit. The quilt did need to be washed afterwards as it felt like cornflakes in the sandwich.
A word of caution.....try the glue on any solid fabrics scraps you have in the quilt first to see if the glue leaves marks. I did a sample on my solid and it did leave marks even after I washed the sample in the sink. If you have a patterned fabric it would not be noticeable.
