Spray 3680003 MAX 1k Self Etch Primer Filler (Gray) 2PK

This primer did an exceptional job of adhering to some aluminum tool boxes that I painted black. With a quick buff on the boxes with a nylon abrasive wheel and cleaning the boxes with Solvent this primer went on easily and evenly. After painting the tool boxes black I was moving the next day and dropped one of the units on concrete and much to my surprise it dented but no paint came off. Now that is what I call adhesion and wii use this product for any aluminum painting projects in the future. In today’s world it is hard to find a product that exceeds expectations, thanks for a great product.

Amazing product, i use it to prime my 3-d printed items.

This dries hard so you must make sure you spray at the right temperature and perfectly clean or else it's going to be heavy sanding to smooth it flat

Although the cans looked brand new and were taped together with packaging tape, one can was only about 1/4 full, I barely got 1 coat on my car roof with both cans...
