If you do, remember two things. First, the cheap WSF material is grainy which makes edges slightly fuzzy and second, it absorbs paint like crazy so a good coat of primer would be recommended. I'm only leaving the material there since it's cheap and nearly indestructible but you are losing the crispness of the mid-range materials. That said, with a steady hand you can block in the colors easily enough and do some quick dry brushing to highlight most areas.
