SUPER expensive a neighbor in mass priced them when painting again this summer. Rhino was literally the cost of four full blown "professional" paint jobs. That being said if you paint about every 5-6 years which is reasonable your payback is around 20 years. My neighbor said he'll be "pushing up Daisies" in 20 years so he'll let the next person worry about it.
Not sure I can argue with that logic??
