Package arrived in good condition no issues. 1. The tube is very hard to puncture. My caulk gun has a puncture tool as part of gun but it couldn’t ********* the tube. Ending up using a small drill bit to get it opened 2. Material is very thin (by design I imagine), but up it continues to flow even when pressure is released from caulk gun. 3. First tube included the micro tip plus cap with insert to avoid hardening. However the second tube I jus started to use did not have the micro tip, and the cap to prevent dripping was completely different. Fortunately I had the first set to use or I’d have been stuck Checked the third tube and is has both the micro tip and cap as the first set. As to how it’ll work on the floor squeeks, I wont know till some time tomorrow when it fully cures. Hoping for the best result. 3 stars for now based on above thoughts, if it does the job it’ll be worth 4.
