Do not buy this. We use this product daily at work. I placed this order just under 3 months ago. We started trying to work our way through the box and all the tubes were solidified.The only option on Amazon's support page was to contact Permatex directly, so I did. They informed me based on the batch number Amazon sold me a box of sealant that was 5 years old, on a product with a 2 year shelf-life. Avoid at all costs.

Good service, but most of the tubes are hard 1/3 making very hard for the product to come out
