Do not buy
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.

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