Plastic Moulding/Trim on Outside of Windows

[Skycop]

In our 65' Globetrotter I have decided to replace the plastic trim/moulding on the outside of the windows. I don't know the official name for this trim, but I do know that itis gray. I also managed to get replacement moulding from a local glass shop.

My question is about the functionality of the moulding (what does it do beside asthetics) and how to cut the corners (i.e. 45 degree or leave them square/blunt which doesn't look as good in my opinion).

Finally, if I am replacing this moulding/trim, is there anything else I need to do in conjunction with this process? All of my glass is in good shape for what its worth. From what I can tell, the moulding is very brittle due to the many years in the sun, but the caulking/weatherstrip underneath is in pretty good shape. I have Vulkeim and Parbond in case I find any problems though once the trim comes off!

Thanks in advance!

Greetings Skycop!

The exterior glazing strips have been mitered in most of the applications that I have seen. In the 1990s, the usual direction was to use a "dab" of Vulcem on the mitered joints to improve the seal. To insure that the windows are fully sealed, you may want to consider removing the glass and replacing glazing bedding strips as well. This would also pose a good opportunity to replace the window gaskets as well to eliminate that as a possible source of leaks.

Good luck with your project!

The original window gasket was very thin and hollow.

The problem with it from day one, is when the window is closed for a few weeks, that hollow gasket collapses and becomes useless.

A much improved "D" shape gasket has now been in use for several years, that has proven to be the "fix".

Thoiusands of owners have switched to it.
