I don't remember who it was but another member had a good idea on filling the drip rails. After he cleaned the channels out good, he tack welded a 1/4" round rod in the channel all the way around. This way there was less filler needed and less of a chance of an issue. I don't remember if he used body filler or seam sealer. IMO seam sealer is the way to go. The seam sealer that markeb01 used appears to be holding up well.
