I've used the spray adhesive method once before and it gets messy and sticky as well as can cause air bubbles. Another tip, let the fiberglass go over the edge a little bit and trip it later. That way you have a strong edge to the piece instead of it being sort of weak. Similar to what it looks like on the top of the bicep. It looks like there isn't any fiberglass behind it.
I've found it better to lay some resin down inside the piece, stick the fiberglass cloth section to it, and then doing the patting with the brush to let the cloth piece get saturated with resin to be a better method. You'll work your way down a piece as you go while overlapping previous sections of cloth.
Also, if you need any help with your road to Recon.. I just found the end of my road to Recon ;D
