It helps, but the tape ain't a decade long solution. Wear is happening. I played around with making delrin rollers, that helped too ( I think it's mentioned in the blog post you linked). But I neglected to try replacing the two smaller rollers that run horizontally in the middle track (post 85 vans). I think a fair bit of noise comes from them.

And yes, damping the resonances in the sliding door skin makes a big difference.
