After seeing the impressive results on Hyperion at Lock & Load, I will be attempting the Hair Spray Weathering Technique as described in the painting guide of Colossals. It seems fairly straight forward, but I do have a couple of questions regarding timing.
Disclaimer: I am bald and have no idea how hair spray works for its intended purpose.
Per the guide, one should allow the hair spray to dry before painting over it - is there any sort of "window of working time" during which one should apply this coat and begin abrading with the stiff-bristle brush? For example, after applying the hair spray, is it OK to wait 24 hours before painting over it, or should the next coat go on within, say, an hour of the hair spray drying?
Similarly, after applying paint over the hair spray (and letting it dry) is there a window of working time?
Basically, I am trying to determine whether utilizing this technique is something I can do over a period of several days, or if I will need to block out a stretch of time to complete all the steps in immediate succession.
Any input or anecdotes of experience are greatly appreciated, thank you!
