Today I am at a dealer I haven't been at in awhile, Integrity RV. This 2012 Seneca has been sold and they asked me to inspect it for delivery. Obviously, I'll check the roof first. This motorhome from Jayco has a FRP, fiberglass re-enforced plastic, roof. Like I said in the video, dicor, Alpha, or Xtrm are all fine choices here for roof lap sealant.
