I stopped at this guy RVFogDr.com
I concur with the RVfogdr recommendation, and as an aside, he does recommend people in other areas when it's too far or impractical to travel to his location.
Last year all six panes of my two front side sections (sliding and fixed, pass and drivers side) started to fog. He recommended a place near Ft. Myers (where I happened to be traveling) and I stopped by - they completed the work within 6 hours by pulling the frames, separating and cleaning the panes, installed new gaskets, pressurized them, and reinstalled with new rubber all around.
Worth every nickel and I haven't had a problem in the 10 months it was,done.
