Great product, great price, great service.

### ⭐ Warning. Old stock. Batch date 08/10/2019.
*by A***N on 29 October 2023*

Product sitting about for 4 years. This stuff does not have infinite shelf life. Primer dries to the touch but does not cure properly and clogs paper while sanding. No longer easy sand. With the time is takes much faster to use 2k primer. I have experience with products like this with 30 years in the refinish trade. Glad it was just metal framing I was priming.
