We’re willing to try anything that makes caulking easier and gets us back to doing something else. The Flextension caulking tube tip attaches to all tubes of caulk and adhesive. It allows you to spread a bead in places that would be difficult or even impossible to reach with a normal caulking gun. Even though this looks like one of those As Seen On TV products, for $2 it can’t hurt to give it a shot.
A single Flextension caulking tube tip can bend up to 180°, and you can connect two or more Flextension tubes for a longer reach. You can remove and reuse the Flextension multiple times, and the included snap-on cap helps keep the tube from drying out.
For some reason the Flextension is a popular product at many boating and RV online stores. You can also find it at more conventional stores like Amazon. Either way, look to spend about $2 to $3 for one Flextension.
