Top Caulk is a revolutionary product. Top Caulk was created to help painters and do it yourselfers, so that they would not have to use their fingers while smoothing the caulk. This makes work much easier, as Top Caulk is very much an easy-to-use product and with some practice Top Caulk makes this work a lot faster as with one stroke you can both apply caulk on the surface and smoothen it out.
