2) As long as you can. Or use bug and tar remover. That may "cut" quicker than the Waterless.
6) Completely understand, but the shampoo will do the same thing, since you already got alot off with the first foam rinse.
10) outside, it won't last at all. Doubt it would last a day. Inside, it actually helps keep your window from fogging and keeps it clean. You can clean the inside with just a microfiber after you have applied the Brilliant Glaze. Here's a video about it:

12) Yea, it'll sling even if you rub it in. There's even a caution on the Tire Shine spray bottle. You could drive the car home and put it on then. The Tire Armor takes like 15 minutes I think, to "cure". The VRT would be fine, but it's not as shiny as the Tire Shine.
