Clear Sealant – Baggage doors, Windows & Clearance Lights
Water intrusion can happen in many places on an RV. The front upper clearance lights are a common spot since the water can be forced in when driving 65 mph in the rain. It’s also good to seal around the tops of the baggage doors and windows.
Roof Sealant
Inspecting and maintaining the roof seals is one of the most important jobs when you own a trailer. Most people don’t do it often as they should, most likely because it requires climbing a ladder and, as they say, out of sight, out of mind. Maintaining the roof seals will keep rain water from getting inside the trailer and rotting the wood.

Step 2 – Clean the sealant

Alternative: Sealant Tape
Sealant tape offers a more permanent and longer lasting solution since it won’t crack like roof sealant.
To install, lay it along the seam and press it down with a roller.
