Alternatives for seal sealer that dries fast and paintable??? Need quick responses!

[BlazerBill]

I’m in the process of painting my K5 but found a seam that needs seam sealer but don’t have time to wait days for it to dry. What is a good alternative for seam sealer that seals well, dries fast and is primer/paintable? Thanks!

I go with 3m everything. Haven't personally used their seam sealer, but I'm sure they have the one you need.

3M is great stuff we heard but an old timer in our area recommended NP-1 and that’s what we used a few years ago. Several here said not good to use for the application for various reasons, but we were not building show truck and didn’t know any better at the time. The NP1 comes in all the colors, and available at Lowes or HD About $7 a tube. Used it on floor repair in cab and to seal bed. We then used raptor on bed over the NP1. So far (2 years almost) with extreme temperature swings here in DFW all the seams are still perfect for whatever its worth.

3M 550c claims 60-90min cure time to paintable skin.
Idk if it’s special as most urethane sealants are moisture cure and skin over quickly. But NP1 claims much longer before paintable.
But if you’re priming right now (you said primer compatible) just prime it then seal afterwards. Should do that anyway. Imo. Unless youre faster than most and priming, painting in the same day.
If it’s exposed sheetmetal I’d think you’d need to sand, etc before painting.
If it’s hidden then carry on and stuff it and seal it later over the paint.
Just tying to give you some options
