OMG! But, if you do, BE SURE IT'S THE UN-SCENTED VARIETY!!! Many, many years ago I attended an NMRA regional convention and toured some of the locals' layouts. One of which...how shall we say?...'stood out'. Seems the chap, in his rush to put more scenery/greenery on the layout chose the expedient thing to do...use his wife's can of hairspray to apply fresh foliage to the tree-covered mountains. Except the hairspray was 'scented'...and the layout spoke shouted "Hair Salon!". Perhaps that dissipated over time. But, I'm sure he grew tired of responding to "What's that smell?"

Separate comment on your inquiry...
Many of us have used chalk powders to weather this and that on the layout. To fix it in place, avoid transfer to fingers if on an engine or rolling stock item, we would overspray with Dullcoat...only to see the weathering seemingly disappear!
So I'd be really interested if there's a new overspray that minimizes/eliminates that disappointment. I've since done most of the 'weathering' using washes and paints, dry brush techniques, etc.. But I'd rather use chalks in many situations.
