Choosing the Right Spray Can

Selecting the right epoxy primer spray can is crucial for achieving the best results. I consider the size of the can, as larger cans are often more economical for bigger projects. If I only have small touch-up jobs, a smaller can might suffice.

Comparing Prices

While I want high quality, I also need to stick to my budget. I compare prices across different brands and retailers. Sometimes, I find that buying in bulk can save me money, especially if I have multiple projects lined up.
