Hello! We have a 1988 GMC Jimmy with a FWC we bought on craigslist. I am not sure the age of the FWC but it's not new... the interior now has a significant amount of mildew and the care of the exterior of the vinyl was subpar. Anyone have any recommendations of who one could call or how to repair some gnarly interior and exterior? The pacific northwest was not kind to this FWC. Thank you!!
