Yes the drip rails are the channels that run down the roof and A pillar. I can't remember what is used to seal them with before painting.I am sure other members can chime in on what they used.
Gotcha...I also just did a search on the rails and mine are in really good condition. The only place I saw rust and slight cancer was in the upper windshield channel. I am going to wire wheel the drip rails and windshield channels tonight and evaluate how much repair will be needed. Should be pretty minimal stuff. I am still curious as where to seal the rails. I already bought seam sealer and auto body sealer from TCP Global and plan to do all that prior to Primer/Paint so this is all good gouge! Thanks!
