What Customers Are Saying

The spray primer provides good coverage and dries quickly, creating a smooth, even surface that is easy to sand. It works well on various materials like metal, fiberglass, and 3D prints. However, some users found it difficult to sand and reported the primer gumming up sandpaper. A few also noted the spray nozzle clogging up. Overall, the primer is effective at preparing surfaces for painting and most customers were satisfied with the results.

Easy Light layers, builds strength and Consistency

Despite my distain for rattle cans, I find myself going through a lot of this stuff for 3D printing. Its quick and easy, sands nicely but fills in print lines saving me from hours of pain staking clean up and sanding.
