WORKS FINE
USED IN RESTORATION WORK ON CLASSIC CAR, REMOVED OLD SEALER FROM WELD AND BOLT TOGETHER SEAMS ON FENDERS AND TRUNK WITH SCRAPPER AND WIRE BRUSHING. WENT ON SMOOTHLY AND FILLED SEAMS USING HAND CALKING GUN, NO PROBLEMS. NO LEAKS TO WORRY ABOUT FOR DECADES TO COME. 3M HAS A GREAT TRACK RECORD YOU CAN TRUST.

Does the job to seal leaks
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!

Really good, but use it all at once.
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.

Applies smoothly, dries-stays flexible, easy to work-with
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.

Cheap, easy to work with.
Seems like good value for the money. I was applying to the underside of my car so it was important that it didn't run, which it didn't. Was very easy to work with. Stuck to the car without sticking to my glove too much while applying.

Works great!
Strong hold, does have a strong odor when applied, clears up when dried.
