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.

used this to reseal a A pillar leak for Honda accord (which is known for this). If you have water leaking in from the A pillar but your door seals (both door and body/door) are both good....then likely you have the same problem. You remove the roof to windshield trim and underneath is your leak. Cleanit out very well, Pump a good line to seal it all down to about mid-windshield and reinstall trim. Depending on amount of beading you put, it can take a few hours to dry.tip: use a spray bottle of slightly soapy dishdet water to help keep this off your finger. It is putty-like but just as sticky as caulk. I found beading it and then spraying and tapping it down with my finger was easier than doing the caulk spread.

I bought this to seal some repair work on my truck, it spreads good, hardens up stays flexible and paints over well, good product.

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

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

Works great
