Last fall I used this product, ProtectAll. I have lived in this house for 30 years and I have always had one or two RVs parked in my side yard. I have owned both Fivers and Slide in Campers and have had both at the same time.Now just have the Monty. Long story short. Our wet humid climate usually causes things to turn green on the north side.
This Montana has stayed pretty decent and we have had one of the worst winters in history. No green at all on the North side. The North side is the High Gloss rear wall, so that might be the reason, but the whole rig looks really good so I am sold on this product.
