to seal driprails: first get on a stool and look down into the channel (on the exterior). this is where the roof panel is spot welded to the drip rail; therefore, there is a seam. the factory used sealer in this spot but after 30 years, it is usually cracked and/or flaked off. if you dont see a crack or seam then you are good for now. mine was flaking off, so i used a wire brush attachment on an angle grinder to clean to bare metal (being careful not to damage the metal). then i degreased the area and ran a bead of seam sealer on the joint, smoothing the bead with a finger. it then needs to be painted. if the joint is a bit rusty, then that needs to be treated first with rust converter. paint wont seal seams.
