my biggest "secret" on the high speed painting is having a good sense of when paint is *just* dry enough for tape... and i only use the crazy $10 a roll super delicate surfaces tape.
the nice thing with rattlecans is that they dry fast and the finish is REALLY tough.
i can lay it down tape about an hour after i paint if the temperature is good. and a small space heater does wonders for the temp.
that and i find layered weathering much easier to do if you don't let the paint cure too much before peeling it.
