I knocked the extension for the right front end of my rain gutter off (I know, DUMB) but I did it. I did not realize that the caulk in the front cap/roof/sidewall joint had been compromised, heck I didn't even know I knocked the extension off, any way, it was a really big space for the rain last week to enter and flood the footwell on the passengers side.
I used some silicon as a temporary fix and it worked fine. Before the rain this week, I removed all the old caulk and silicon and replaced it with the vertical application formula of Dicor. I did not like the appearance of the caulk and really wanted a smooth high point to low point drainage available. I though what the heck, I'll use my finger and clean it off later. I had a couple of things to do before I climbed the ladder and it was 15 or 20 minutes before I got back to leveling.
During that short time a skin formed on the bead line I had made and as long as I pressed softly and did not swipe the caulk, it was easy to work with and make a nice smooth bead without smearing it all over my finger. I do feel that the Dicor is the stickiest stuff I have ever caulked with. I can understand why if you prep the surface well it makes a good bond.
Had a little sub-tropical cell come through after the repair and success, no water inside.
I don't think that our roof has ever been re-caulked and Winnebago recommends re-caulking every couple of years to keep the roof from separating from the RV. My DGS is raising money for his trip to Virginia for the National Scout Jamboree and I'll pay his at least minimum wage to help. Besides it is good to know how to do a lot of household chores and keeping your roof sealed is also a household chore.
