I'm trying to insert the rubber weatherstripping into the windshield frame of my '26 roadster. And also into the stanchions. Is there a trick to this? I'm afraid of marring the paint.
Try hand soap as a lubricant.
We do it all the time on modern cars where rubber components are slid on metal components (like glass runs or door surround moldings.)
We use soap because it is cheap, doesn't stain or degrade the rubber and washes right off with water. It also does not dry your hands up, if you are in it all day.
Thanks. I'll give it a try.
