re-caulking windows

I just removed them, don't have much to clean up if it comes out. I used the butyl tape in a roll from Lowes.

On my first 2 RV's I did that but on my current 2003 I just scrapped away the old and resealed with new

Have to admit when the small window above sink started leaking and I got the quote and time to take it out......I put clear silicone around the edge on the outside. Can't see it and several years later no leaks.

Removed the old caulk, cleaned it all up, applied new caulk.

I removed the silicone along the top as much as I could and recaulked w/ silicone and that stopped the leaks.

Mine is almost 20 years old. I had no leaks but just for PM I put a small bead of clear around all tops and sides of every window a couple of years ago and still no problems and you can't even see the caulk.

2003 and you are resealing the windows? wow.

Clear silicone has always worked for me. Even the cheap stuff does a fine job.

I would highly recommend removing the windows and replacing whatever sealing they used with butyl tape. This will get you much a better seal than just a bead of caulk around the outside (which you can add anyway, if you want), and also it is a great opportunity to check for water damage.
On my rig I took the windows out and found that 2-3 had been leaking since they were installed because Coachmen didn't install the foam rubber tape correctly. After replacing the window a pizza cutter works great to slice off the extra butyl. You can even run the pizza cutter at an angle to bevel the butyl to shed water better.

Got the tape from Camping World.
