My rear window seal was leaking pretty good into the trunk. The PO had the rear window replaced about 4 years ago and they used the old seal. They used lots of putty and silicon sealant to attempt to get the old seal to not leak.

I have the window out and have the new seal. I have cleaned up most of the old putty and silicon. I found a couple areas with pits(gouges) but with no rust(see pict.). I have a couple of coats of POR on the areas. I am going to put a coat enamel paint over the POR as well.

The top portion of the window frame has limited putty but it looks like the orange colored material is adhesive used to attach the headliner. I am having a hard time removing it. Should I even attempt to remove it? Does the frame need to be super clean? The putty on the top of the frame has been very tough to remove.

Can anyone think of anything else I should address while the glass is out? Anything to consider about the headliner?

Is installation a DIY or should I just get a pro to do it? I have the (67-200 Removal and installation of back window) from the manual. The directions call for use of MB window sealing compound(PT. # 001 989 31 20) to be used between the glass and rubber frame as well as body and rubber frame. How difficult is it to get the new assembly in around the headliner?

Thanks in advance for any and all input.
