Pros

Works in any normal caulking gun. Works just like regular household caulk using the same caulk gun. Pierce the foil on the nozzle end, install the nozzle, and cut nozzle if necessary.

Levels extremely well. Have used extensively, love it. Worked really good and is still pliable after a year. Works as advertised. This stuff is awesome.

Easy to use and cleanup. Follow 3m's directions. Then reassemble everything. Wear nitrile gloves and smooth with your finger.

This seam sealer is easy to use and spread. Sanded and resealed my entire c4 corvette firewall with this product.



Cons

Product was shipped without the applicator nozzle. Tip is clearly shown in product pictures.

    I would suggest buying the replaceable tips if the whole tube isnt going to be used as soon as it is opened
