Brace yourself. Here are a few from a novice:
Wait for MM to fill in gaps and fine-tune this with corrections, but I'll try to start thinning this list.
1. You can use black curtains (or even darker light-absorbing fabrics on curtain rods) for infinitely adjustable side-masks easily enough. Top/bottom adjustable masks can be a little trickier..I used black fabric-wrapped 10ft steel poles to basically make my own black roller-blinds and put a few small screws into the wall to make pre-defined stopping points.
I've also seen people use solid panels that roll into different positions, but the curtains are a little harder to mess up and much less expensive.
2. You'll want to tape-off any surrounding areas you want to keep unpainted and then apply the actual paint in large sweeps that begin and end well outside of the lines..this helps keep your speed consistent whereas trying to stay inside lines will make you end up with too much paint near the edges.
3. It is very important to get a smooth surface for any reflective screen. If you really doubt your flat/smoothing abilities AND can't borrow/bribe someone with more experience to help, you might consider getting a large smooth substrate or panel to attach onto the wall and paint that. It'll add to the overall costs, but give you a perfectly flat/smooth starting surface right from the start.
4. The important thing is that you prime..the brand, less so important. MM can tell you if what you have is extra thick/thin compared to the Killz, and you may need either some extra thinning or extra coats, but it should be fine.
Usually 3 light coats are recommended, and you should lightly sand the entire surface again before the last coat.
5. Spoons should work though some where using measuring syringes I've heard, but the important thing is to make sure you aren't leaving enough mess on your tools to be throwing off the amounts. The water listed for rinsing is kept for the colorant mix (both for thinning and for using the ingredients that would otherwise get washed down the drain).
If you're having trouble with the conversion, you can scale the amounts to better suite your measuring increments as long as the ratios stay the same..I'm only talking about the colorant mix here.
For example: a teaspoon is 5ml..
A hair less than 3tsp blue
Mix that all together and you'll have 8oz of colorant component.
7. You're aiming for an overall consistency similar to thin tomato soup using the filter to ultimately judge before spraying. Start low and add in small increments until you get the target thickness/viscosity.
8. Oops, already covered this in number 5.. I also just realized your list has no number 6.
9. 6-7Coats is recommended..it's better to have more thin coats than fewer thick ones for the sake of the finish. You can get drying time down to 30minutes for the first few coats with fans but the later coats will need more time and it's really better to not rush this.
10. All the versions from 1-4 are said to have over 1.0gain, so you've got plenty of leeway. If your room will be stuck with light-colored walls then a darker SF would be best (3-4) whereas a 2 or less could perform very well in a darker-colored room with a bit more lightcontrol.
