CMP window rubber and plastic

[Pedro Bedard]

The first thing I'm working on for my CMP are the windows (since that's all I have access to at the moment) and was wondering where to get the rubber that was between the window frame and the thin steel slats?
Also, do you guys recommend Lexan for the replacement plastic?
Lastly, what do you use for paint? I've stripped them down to bare metal at this point and straightened the bends. I was planning on using a basic grey car primer but need to know what is usually used as the main color for a CMP and where I can get it from.
Thanks!
Here is a photo of the first window;


And the second one;


They're both clean, stripped and straight now. I'll get pics of them up soon.
