Great product you must use acetone to clean gun.
You can get a reall good gun off amazon for about $50 "TCP Global Brand Professional New 2.5mm Hvlp Spray Gun". It will lay this stuff on perfect! I cant say enough good things about this primer!

Questions & Answers
Can this be sprayed on top of rattle can primer?
We can not guarantee compatibility with anything we do not sell. You would have to test a small area first.

I mixed up 16 oz., used a drill to mix well, new gun with 2.0 tip. Material sprayed fine but went on thick & speckled with tiny gobs (like sand) all over the panel, why? It sanded out fine. Can this be reduced to spray lighter as a final primer coat?
This product is not recommended to be reduced. However, this product will have a slight texture to it due to the high build finish of these primers.

What is the best method to measure out the catalyst in 1/2 or 1 ounce portions?
I looked up on the internet figures as to how many drops are in an ounce, etc. As it works out, about 9 drops of catalyst to the ounce of material (closer to 9.25 actually, just get as close as you can). I've been using this method for mixing up 4, 5, 10 ounce portions etc, at a time and it's been working great.

The description says this can be used on bare aluminum! Yet at least 2 people have specifically asked about that here, both answers were to always use epoxy primer on aluminum first. So, which is it, can you or can't you? Maybe some factual consistency?
USC High Build Primer/Surfacer(50776ZP) is a high quality Direct to Metal(DTM) Primer Surfacer that has excellent adhesion properties and will work very well on bare Aluminum when the surface is prepared and cleaned properly.

Can i use under an acrylic urethane sealer and paint and do I need to thin it with something ?
Our paint is acrylic urethane based and is perfectly fine underneath. We can not guarantee compatibility between this and brands we do not offer in general though.

So technically, I can grind a panel to bare metal, bondo imperfections, 120# the whole panel (or vehicle), apply this, dry sand with 400# and go right to base/clear? ("Technically"! Not saying I wouldn't use a sealer.)
Technically Yes!! This is a Direct to metal(DTM) product so it can be applied to bare metal and will fill 36 grit grinder marks in 2-3 coats. Then 400# sand and paint.

Besides the prices, what exactly is the difference between this and Contour? Featherfill?
All three Polyester Primer Surfacers you mention perform exceptionally well. They all have similar properties and are great at filling (high build), fast drying to sand times and are easy sanding. Other than cost, personal preference and past experience is usually the deciding factor.

Can it be reduced with acetone?
The manufacturer does not recommend reducing. It can negatively affect it's properties.
