I find if I lay all three layers down at once, smooth layers, clamp so one side is held firmly. Fold 1/2 of the top 2 layers back, spray the bottom layer, wait a couple of minutes to dry, bring the batting over the layer on the bottom and pat, don't rub, the entire part of that you just sprayed, repeat with top layer. Then clamp the other half and repeat the steps above. We finished, let the quilt rest awhile before taking it off the table. We usually have two or three people to help because you want to be sure there are no wrinkles. You can always take up the piece you are working on if necessary without re-spraying.
