What is the differance between 501 LSW and 502 LSW? In my search as to what to use around my skylight I was getting conflicting info, Dicor lap seal, or elastomeric sealant, so I emailed Newmar and they responded to use Dicor 502 LSW. I have already used 501 LSW to reseal the perimenter of the roof, hope that won't be a problem. This is on a 1999 Mountain Aire with a BriteTEK roof.
