I have used 505 and Dritz ( I can use coupon at Jo'ann for both). I like both equally , big tip do not spray too much. Both take a few seconds before they fell tacky , hence the urge to spray more. I pin the perimeter of the sandwich as both will still lift at the edges from repositioning the sandwich while quilting.
When I found spray basting.... it was life changing for this quilter. I just dreaded sandwiching plus I still got huge puckers on the backside...... now I can proceed with confidence. I do take my cold iron and press the layers and each step , first the backing and the batting gets the iron to really press the fibers together( I flip and check for any signs of a pucker) , then after I spray the next layer and position the top on the batting I use the cold iron again to really adhere the top to the batting.
