What are your experiences with the newer snow covers for the layout blinds? I have always used the spray on snow from x-mas time and it works great. just a biatch to get back off later without haveing to use a hoses then the blinds are soaked and a mess to haul. I was loking at the snow covers and they look cheap and not to durable. Whats your experiences with them? I have 4 Avery Finishers.
