Silicone around windows

Never heard of polyurethane before. Will look into that. I guess they should also sell that at my rv dealer.

Won't need to go to an RV dealer and pay their high prices. Any big home improvement store will have it. It's around 5-6 bucks a tube here in the States.

tape chalk under window trim. never silicone, always use rv dedicated chalk or tape.

Agreed - No Silicone!! Silicone is bad news for any exterior sealing efforts.

I make a lot of money doing extensive repairs and rebuilds because people insist on using silicone to seal things with!!

I used to use and recommend a lot of polyurethane caulking, until I did a test on my own TT. I resealed my corner moldings with it and it came apart and split after a year of travels.

About 2 years ago I started using Titebond Weathermaster for all my solarium builds and repairs. This stuff is amazing! First sealant I have ever found that will actually stick to wet mill finish aluminum.

It is a polymer based sealant and so far I have not had any issues or failures with it.

It has huge joint movement, which is important for RV use. It stretches like a rubber band. It also cures to a stretchy soft rubber like consistency. Tensile strength is excellent. I am using it extensively and really find it superior to anything I have used before.

I use it for sealing glass to aluminum and different flashings, trims etc.

No silicone on my rig, nothing will stick to it. Not even more silicone. :)

I don't use silicon on anything. Once you put it on nothing else will stick to it. I use a polyurethane caulk. There are several brands on the market. I use one called Quad. It's available in several colors from many of the big box stores. I e-mailed the manufacturer and was told it would be excellent for what I wanted it for. It has held up well. I generally tape off both sides of where I want to put it. That way I can get a nice straight line. No reason to do anything to the roof if it doesn't need it. Check for shrinking also.
