My back window is a bit loose. I have the new rubber strip between the window and the deck lid. I plan on having the window professionally resealed with the new rubber strip added.. Will they have to take out the back pad to do this?

Yes and the rear pillar pieces as well

just go buy some buylt and do it yourself easy smeazy

Here's a write up from my website that shows how to install the butyl tape and rear window. You can check out the site on how to remove the back pad and associated trim pieces and the rear window. You can do this yourself and save a ton of money....
