Clean all surfaces with acetone first for best adhesion. Product works well and levels nicely. Hot dry days are best for working with it.

This product did a great job on the RV roof. Self levels well, it is very liquid and designed for the top of flat surfaces, would not recommend for walls as it will just run off. It says it dries fast but mine was still very tacky after 24 hours. After two days it was cured very well and looks like it is there to stay. Great product for roof top applications,

Product was a little more runny than I would of liked it but other than that it went on excellent. Fast delivery.
