I used 3M-8329 controlled flow 2 part seam sealer for the drip rails. The stuff is really nice. I first cleaned the drip rails, then epoxy sealed the with PPG DP90LF. The roof, rear deck panel, edges of the trunk jam and the rockers have 3 coats of PPG K36 urethane high build primer on them and they have been guide coated. They will be block sanded by hand with 320 and possibly re-coated if need be.
