Review on 3M White Urethane Seam Sealer - Permanently Flexible, High Solids, 310mL/10.5 fl oz Cartridge by Dean Wilson

I bought this brand mainly because of the name but it works well. I put it straight into my caulking gun and started using it right away. It really flows the way a bead "sealant" should. As far as I can tell, it's not free-flowing or self-aligning. I used a Bondo spreader to spread it smoothly and evenly over the joints after changing the bottom of the car. I also taped the intended coverage area and after I finished applying the sealant I pulled up the tape. It hardens to a rubbery surface. It also doesn't tear or tear easily. I like it.
