Faded/no gloss at main garage door. Applied Rocksolid Polycuramine 7 days ago and everything was fine, until today.... Did I say it was applied only 7 days ago?! Called Customer Support and was told this product does not have UV protection. I said I applied this 7 days ago and the max time my floor has been exposed to the sun was 15 to hours, in Iowa in the spring time with max Temps of 75. How is that possible? I said it is with the roller marks, it is possible there was a defect in the last bag I used, which is where this problem started. I used the same process as the other two bags and this one seems to not maintain a high gloss appearance. I was sold on this product for the past six days, now I regret it due to the variation/durability and the fact Rust-Oleum is not standing behind their product.
