The Proper Way to Paint an s14, Window Removal

[stunnaben]

Guys I've taken on the task of painting my car myself. I bought a body kit some time back and I've been working on that getting fitment good and fixing the cracks it had in it from the PO. That's going pretty good and everything and now I've gotten my 240 sitting in my garage and I'm starting sanding. I want to pull out the rear quarter windows on both sides and replace the trim around the front and rear glass. I know the rear glass trim is an easy job so I took it out. The rear side windows however are proving to be confusing. I've looked on the nissanparts.cc site and it seems you can't buy replacement trim for those windows. My trim at the top has over the years started to pull away from the body maybe a half a cm or so and I'm wanting to do a good job painting this car so maybe someone in here can tell me if it would be easiest to just remove the window to fix it or is there a way to somehow push it back?

Thanks again fellas.
