Id suggest not spraing 3m77, if you get a wrinkle your screwed.

Read this on the poly coatings.

I use West systems

I agree heavy is bad.

I spray it very lightly holding the can 2 feet above the work. Just a very light mist and you can stll reposition the cloth as long as you have'nt push it down firmly. When I didn't do this the very thin .56 oz. cloth weave would strech just from spreading the resign or tring to pull out a small wrinkle.
Some folks use inexpensive hair spray in lieu of 3M spray. I use Minwax Polycrylic and a foam brush wide enough to fit inside can. I work from center to edge. It is water based so most of the weight evaporates. I have used the same foam brush over and over because it is very easy to clean with warm water. I was thinking of adding Microballoons to the Polycrylic to save time with finish sanding. I haven't tried it yet but will.
