Rob,
My use is .25g/in^2 of material ... both resin and hardener. And even at
that the layup is still wet. I guess you're more tollerant of waste than I.
Admittedly I keep the waste cloth to a minimum and make epoxy quantities
based on exacly what's needed. And you use excess for other things .. good
idea surely .. I can never plan for use of that extra in the bottom of the
cup. I either forget to prep the area or have another crisis to attend to.
Thought eveyone might like to know what a miser uses on layups tho.

Even in my miserly condition, I still have used a bunch of that sticky
stuff.

Everyone has a "method" for applying resin to glass. To avoid bubbles and
waste, I tape the plastic down and populate it with resin in the boundries
of my layup. Spread it with a squeegee just thick enough for the glass to
absorb it all. Lay on your glass. When the glass is wet (has absorbed the
resin), smear more epoxy on the top if needed and add any additional layers
of cloth one at a time with more smear of epoxy. There are no bubbles using
this method! Then lay another plastic sheet on top of the layup and roll
roll roll. Then I use that neat cloth cutter to finalize the shape of the
part. Carry the masterpiece part to the job with the top layer of plastic.
If you trap bubbles between the wet layup and the job site, take a paper
towel wet (damp) with acetone and push those bubbles out from between the
layup and jobsite, very easily, without muss. If I still have bubbles or
something I need to work, use a brush with out removing the brush's plastic
cover to work the problem. Remove the final layer of plastic from the part.
Cover with peel ply, if desired, till cured. Wonderful layups.

Thanks to all on my flap mounting questions. I'm moving ahead.
