Started working on the drip rails today

Guy at FinishMaster suggested this. It is what he uses. Not self leveling but has about a 30 minute working time. Figure I’ll try it in the vertical parts and if I like it keep going. If not I’ll stop and use a self leveling sealer on the horizontal.

I just went through a bunch of seam sealing for the first time. Vertical surfaces do require the heavy body stuff (or the medium body self leveling if you can), but I wouldn't use it for anything that would show, once you get a peak it's always there. I would buy both types before you start. I used SEM brand.

I would also suggest using painters tape liberally to keep the lines clean and the sealer where you want it. Before the working time is up, peel the tape up and you get a nice edge.

But thanks for posting this, I'll be following along as the PO of my truck used bathroom caulking for the drip rail. I'll be hopefully fixing it before the fall.
