We sold Extangs since '92 and had very good luck with them. The customers liked them and if you do have a issue there service dept. is great. Just wash them with a car wash soap and use a good protectant on them. They sell there own protectant that is made buy 303 protectant. I use Meguiars Mirror Glaze Vinyl & Rubber #40 protectant. Part # M4016 is for a 16oz. spray bottle or #M4001 for a gallon,this is what I buy because we use it on both trucks vinyl & rubber.
