3M Dynatron Auto Seam Sealer Caulk, 550, Grey Color, Permanently Elastic, Fast-Skinning, Non-Staining, Non-Sagging, 12 oz

Work great

Used this to seal some weld seams on my truck that were leaking. Applies with good consistency, dries pretty quick and can be painted to match if you wish. Does the job well!

Great Seam Sealer, applies smoothly, odor is not too bad at all. It does have fibrous content in it, so it can only be smoothed out so much. It dries very quickly too, so you do have to work fast. Overall it seems to do a great job

This product worked really well. I sealed my T-Tops, and the rear windows which were starting to leak after 27 years. The only reason it did not get 5 stars is that even though I sealed it, the back side of the can hardened and I was unable to use it after letting it sit for a couple weeks when I went to use it again.

It is a high-quality sealant. it remains flexible and dries well. It flows easily from the cartridge and is workable. The excess peels are easily too.

Works great
