I will stick to the 505, it sprays on so nicely and stays sticking until I am done quilting. Some of them have been very large quilts and I have not had a problem. I do watch and get it on sale if I can. If by chance I venture into a quilt store and they have 505 at a reasonable price, I pick up a couple of cans. I have bought the smaller size for 12. and that is here in Canada. Mind you yesterday at a shop hop there was a can for 19.00 which I thought was a little pricey. It is good stuff, trust me I have tried other brands.
