    Dumb question, I know, but I am not exactly sure. I assume seam sealer is the last thing you apply after you apply paint, POR-15 or whatever you use. Thanks!

    I don't really think it matters. Now adays most seam sealer is paintable.

    I am going to apply mine before I paint any POR on.

    Got it, thanks. Any brands of seam sealer stand out above the others?

    por-15 first then when everything is nice and dry apply seam sealer otherwise those unprotected parts can start to rust under the seam sealer.

    Won't the POR15 "seal" the seams then? Why would I not want to push the sealer into the seams then paint over it? The POR would just bridge the gap I would imagine. I plan on using a dual tube caulk gun type sealer...

    I would think eventually the seam sealer will contract/expand or crack leaving an opening for moisture to get down into the seam. If I were going to go so far as to put down POR15 I would put it directly against the metal.

    POR-15/primer will rust proof the gap, seam sealer is only to fill in the gap. Put your primer or POr15 on first, then the seam sealer over that (if it a paintable seam sealer) then paint the car.

    Normaly seam sealer is not applied over bare metal. Altho 3M does have one, I prefer the peice of mind having a 2 part primer under it.

    Personal opinion but the only place I've found for por is inside inaccessable spaces(frame rails and door shells)
