Bret,
I've been thinking about the layering thing, and it wouldn't be too hard to conduct an experiment, I don't think; a real experiment.
Imagine a 2" square piece of painted sheet metal, and a scale or balance accurate to a thousandth of a gram; would that be accurate enough?
Apply AIO and SG, then find the mass of the piece. The next day, apply SG again, and find the mass again.
I would suggest doing this with one coat, on a number of samples. That way you could get a reasonable estimate of the mass of SG needed to cover 4 square inches of paint. Then you could see how much SG is in the second coat; Is it a full layer, or does SG increase the density of the polymer net?
After doing this with, say, 50 samples, then see if a third coat adds the same amount, or more, or less. Ditto 4th, if you want to.
IMO, this would be the easiest way to find out about layering. Perhaps The Guru Reports would like to address this possibility? It's much more scientific than a bunch of people looking at SG and agreeing that it looks better after 5 coats, or some such. I think the hardest part would be finding an accurate enough balance or scale. But that would be a lot easier than getting someone to put an electron scanning microscope on your car.
Just a suggestion,
Tom
