mine came with nozzle
I have used 3m products for years. Always dependable. Missing nozzles do occur. They sometimes fall off during handling. These tubes don't come wrapped. It happens. I have had it happen myself in my work shop supply cabinet. I once wrote 3m and and was immediately sent a replacement. They are a good company. I trust 3m. The $19 for a 1/10 gal. tube is a good price. bob

Product Quality
I wish there had been a clear version available. Outside of that I liked the product and the apparent adhesive qualities. The true test will be its sustainability in properly preparing and adhering two resin vases to a granite headstone. Hopefully it lasts for a very long time.

Easy to use, 10 oz fits in a caulking gun
4200 is some great stuff. Nice because it's not permanent but still seals great. The bottom of the 10oz tube has a metal opener on it. Basically, it looks like the top of a grease gun. They do this to provide a better seal on the bottom of the tube so the product doesn't get ruined while sitting. Remove the tab and the bottom has a plunger for a standard caulking gun application. I wanted to put this here because I was confused by the seal, so hope it will help others.

Can’t go wrong with this stuff
Can’t go wrong with 4200. Works great and is removable. The 5200 is permanent.

L'ho utilizzato per incollare le valvole di scarico e i porta gomma del wc nautico. Ottimo.

Great product ! Easy to apply. Used it to repair a fibreglass trailer. Results were better than expected. Easily sanded off the excess adhesive.

Used this to seal the bottom of my leaky aluminium boat. Amazing adhesive that sticks to aluminium and does not wash off. Used it on another boat over 5 years ago and still water tight.

Desde que conozco esta marca es la que uso. Quizá parezca cara pero es muy eficaz.
