Why does EPDM require an additional coating between it and the weather?
Normally it doesn't, in fact Alpha Systems which produces much of the EPDM membrane used on recreational vehicles suggests you do nothing with EPDM other than to wash it occasionally. EPDM rubber is white on top, black on the underside, and does naturally chalk over time, effectively thinning the material. Once you see black showing through that's a sign it's time to coat the membrane to restore some thickness to the material.
