Allen don't use plex on the windshield use aviation lexan plex will discolor in short time and will shatter the lexan wont its only a couple bucks more expensive so your tight asse can afford it as for 12 v electric heaters i'm not impressed get a espacher or wabesto fuel burning unit it will keep you nice and toasty while consuming your dr rums.
Well Crap ! I think i'll just get some new goggles and a thicker coat and gloves . This is getting way to involved for me . Maybe I should just hire a guy to plow ????
