Id go with Arma Coat vs the other brands. Ive looked at them all and like the Arma Coat the best. Arma coat is sprayed on hot so it bonds better then the other brands.

Take a look at all of them and make a decision. Linex is really hard and tuff. Ryno is a bit rubbery and sprayed on cold. Arma Coat is right in the middle. Whatever you get I would recomend you take the surface your going to cover down to bear metal, the material will bond much better.

Most of the companies have life time warranties. Should be places in your area for each brand.
