Well hello everybody I'm new to the website. I'm also new owner of a used national dolphin and I was going to repair the two fogged windows on the pilot and the co-pilot windows. Come to find out my windows do not have a metal retaining ring on the inside of the RV it has a rubber insert that goes around and seals on the inside there is a double stick tape on the window frame that supposedly holds the window in place. I cannot find this tape anywhere please can somebody help thank you in advance
