My Buying Guides on Spraymax 2k High Build Primer Review
What I Looked for in Spraymax 2k High Build Primer
When I started looking into Spraymax 2k High Build Primer, I wanted something that could do more than just cover bare metal.

My First Impressions
The first thing I noticed about Spraymax 2k High Build Primer was how professional it felt right out of the can.

For me, that gave it an edge when I wanted a finish that would hold up well under topcoat layers.
Application Experience
From my experience, the spray pattern was fairly even and easy to control.
