Hi everyone! This is my first post here, I posted this question in another popup forum, and was rewarded with rude comments, so I was advised to come to this forum...its much better! We recently purchased a new to us camper. Its a 1999 Jayco Eagle. When we were out shopping for it, it was a very rainy day...perfect for finding leaks! (or so we thought!) We set it up in the driveway to clean it and get it ready to go camping for the first time. Well, of course, don't we get a crazy downpour for like 3 days straight. Upon checking it during the rain, I noticed that the canvas (or whatever the material is, apparently, according to the other forum - like how dare I say canvas!! They haven't put actual canvas on a pop up in 30 years!!! how stupid am I!!!) was soaked right through on one of the window flaps. Enough to get the bed beside it wet. The others were not like this, and it was definitely not condensation as someone else suggested. And it wasn't coming from the seams, or one spot in particular. The whole flap was wet. So, I am looking for some suggestions on what type of waterproofing I can put on it to fix the problem. I live in Ontario Canada, but I am on the border, so I have access to state side shopping (Just in case there is a better product over there) Any suggestions would be super helpful! Thanks in advance!
