Like NDesign, i started spraying RCS mask, and the results are fantastic. Really, only needing 2 reasonably heavy coats (so the mask looks opaque-ish). Seems easier to cut and remove, i guess it's more consistant coverage than brushing on
as for force drying, i leave them nose down on a radiator, upright against a wall and they're dry within an hour usually. Means i can have 10 or so bodies masked in a night
