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

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

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!

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.

nice and safe in the box big enough to hold a large dog. plenty of mega bubblr wrap, thanks, guys

Works well, as you would expect from 3m
