Any and all suggestions will be much appreciated.
I am also chasing leaks. I assume it will be best to strip the clearcoat before sealing the roof penetrations, windows, and seams? The PO put sealer (silicone and others) on everything including the windows. I have been out there for the last week in heavy rain and water is coming in everywhere. Again, any and all suggestions are appreciated.
The only real way to solve the leak issue, is to strip the trailer.
That will remove all the old clear coat, which would be a sealer barrier, as well as the old silicone sealers.
Then, you can properly seal all the seams using Vulkem for the large seams and Par Bond for the small seams.
Replace the sewer vwent pipe cover gaskets, and seal around the black pipe to gasket area, when you do.
If not already replaced, you will probably find the window, access door and entrance door gaskets have all gone south.
Clean the glass to metal frame gasket on all the fixed windows. Apply Vulkem sealer to completely cover that gasket.
Apply Vulkem sealer to the top and sides of all the windows.
Inspect all the sheet metal seals for any gaps, and correct as necessary..
Replacing those, and sealing properly, will complete the water leak problem, other than perhaps any missing rivets.
After the window gaskets have been replaced, adjust all the locking latches.
That should complete the project and make the interior of the trailer, waterproof.
At a later date, if you wish, you can reclear coat the trailer.
