If you are able to do the work yourself there is a product that I think is a bit better and you can roll it on yourself. Monstaliner.
The biggest pain in the but is masking stuff you don't want coated. It's completely UV resistant, comes in tons of colors and doesn't have any fillers like sand or rubber chunks. You create the texture during the application and there aren't any pockets that will allow corrosion.
Just a suggestion.
