No Caulk Gun Included
Product worked as described, but did not receive the caulk gun in the package deal. I purchased another package deal and hopefully the caulk gun will be included.

The real deal
This is the real OEM product. Was a decent price and came with a caulking gun.

Best caulk you can buy and free caulk gun.
This is the best caulking sealant out there. Very flexible and adheres extremely well to most everything. But still paintable. If you want a caulk that will last , this is the one. A little extra cost, but it applies so easily and performs so well, less can be used. This results in a lower installed cost. You can not go wrong with this! Was packaged well and quick shipping. Competitive price and caulk gun was a bonus. Good quality gun.

Pleased with initial installation, however, after a year, not as happy
This went down smoothly in the expansion joints on my driveway and looked great through the first winter. It did not hold up well the next summer and I had to touch up quite a few places where it pulled away from the edges of the expansion joints. I expected it to be much more elastic. I touched it up recently with DAP driveway caulk.
