On our last motorhome, which was a 34 foot Tiffin, the windows were sealed only with butyl tape. We removed windows, cleaned up old butyl tape and reinstalled.
Our current motorhome, 1999 Bounder has what looks like clear silicone covering the upper edge and running around the upper radius corners and down the sides 3-4 inches.
My question is should I replace the silicone as it came from the Fleetwood factory? If so, any ideas on getting the old silicone off? I was thinking a plastic razor blade or one of these rotory bristle brushes on a die grinder.
