We just made an offer on a new trailer and the dealer is trying to talk us into purchasing Duratain (www.duratain.com
) protective coating for the exterior, as well as interior textiles, awning, and undercoating. We're not interested in the interior or undercoating but question whether this "coating" is really needed on a new trailer or not. What are your thoughts? We will be storing it outside but with a full RV cover. This is new to us so that's why we need your help. We upgraded from a tent trailer that we kept garaged.
