Review on 3M Urethane Seam Sealer Car Care by Joel Norfork

Purchased for use on my 1981 Datsun/Nissan 280ZX sports car when I was remodeling the engine bay and needed to replace all the seam sealing. This seam sealer is easy to use. and distribute. I put on nitrile gloves, just smeared it with my finger and spread the sealant along the seams. If you don't think you're going to use the whole tube at once, I highly recommend getting a box of spare tips. They're available here on Revain, although you might need to do a little searching.
