### ⭐ Review
*by D***R on 6 April 2025*

Great product if I had an applicator. As other reviewers have noted, received sealant without applicator nozzle so I am unable to use. I figured maybe seller would have corrected this problem but I figured wrong. Tube is in good shape though. MFG date 01/29/24. "Free" returns means a 70 mi round trip to nearest UPS store.
