Still prepping for paint.
Started to wire wheel the POR out of the window channels and found a nice surprise on both the front and rear windows. That white stuff in there is just filler globbed into a wide rust hole of nothing. Both lower corner have it bad too.
Got the car stripped down further for paint and since I couldn't figure out how to get all the crusty seam sealer out of the rain gutters, I decided to just shave them off.
