I'm glad they are under the hood. I've alway had problems with the wiper mounted sprayers freezing up. Either they froze up or ice built up on the wipers themselved and blocked them off. Either way I just never cared for the design myself. With luck my Camaro will never see the salt of winter anyway.
also drives a heavily modified Jeep Wrangler. It has LED headlights and wheel weights blacked out with Plasti Dip. It's Baller.
