I'm cleaning up my floor pans & need to replace some of the seam sealer. I'll be using POR on the pans. Will POR stick to the 3M seam sealer or should I POR them first & then do the seam sealer?

Thanks!

The por will stick to the sealer fine, but I'd por it first anyway.

POR first. As the sealer cures and then ages, anything on top of it will crack and\or peel.

That's what I did, POR first then sealer and then after the sealer dried I used POR over it.
