My sister and I have a 23 yr old "stickie" that has sprung some leaks
. (I have an Escape). A well-respected rv repair and supply place in Santa Rosa, CA (Marlo's) has been using Eternabond for a couple of years and Allied trailer supply also recommends its use. Roof Leak Repair Products & Sealing Tape | EternaBond®
This might be a solution for an easy repair for those less talented. (Like me). Since it is pricey and we aren't going to keep it, and we recently caulked the roof, we haven't tried it. The leaks
are around the windows
, so we are going to caulk. One warning re: eternabond-apparently it will not stick to silicone, so that would have to be removed. According to their video clip, it will adhere to previously "repaired" places.
I am considering usage around my square or rectangular vents as preventative maintenence, and wonder if any fgrv owners have used it and wih what result. It is supposed to last for > 15 years.
