When I bought it used in 2005, my Dodge had a nice, if overly-luxurious "power-slide" (IIRC) rear window. At some point, when loading the truck with some logs or whatever on my downsloping driveway, one bounced up and smashed it fatally. Insurance covered the replacement, but the installer said he couldn't get the same model, and instead put in (against my objections, but what else could be done?) a vastly-inferior version with a split pair of manual-operation sliders that don't like to be moved when needed, and don't seal worth a crap when closed. Additionally, I think he did some damage to the paint around the gasket, because it started rusting not long after that. And now, there are actually some tiny HOLES in those rust-patches, which extend up into the space behind the gasket, so there's no easy fix. (This may also be the source of a leak that's prone to soaking the padding under the carpet on the driver's side, though I'm not clear on how yet; I de-carpeted yesterday.) Do many people have strips of rust popping up below their rear glass?
I'm thinking I will need to pull the window out to repair and prevent accelerating rust, and soon, but the window frame itself (aluminum within the rubber gasket) is offensively crappy, with all kinds of crud now accumulated in the bottom channel between the rubber and the window frame (photo) and the aluminum apparently in a race with the nearby steel to see who can become a powder the quickest. (Recent epic storms have also accelerated algae-growth...)

Is this just how it is? Are there no better-engineered windows out there anymore? Amazon and Rockauto didn't inspire me with any selection. I'm thinking I might just go back to the single-lite non-slider option.

Pressure-washing not advisable.
