I am in the middle of a restore. I took off the drip rail aluminum trim. I ended up chipping something out, Sealant?, out of the channel where the drip rail and the roof skin seam it. Was that something the PO did on his own to seal the seam as to not get moisture in between the seams? If so what should I put in there when I am ready to go to the next project on the car. I have an 81 base model.
