Collection: Primer

"I wet sanded and buff/polished everything on a regular basis. When I used this block, it was a game changer. I was able to see the orange peel as I sanded. When it was done, it looked like glass. There were no ripples or any waves left."

"Blocked over standard block. Wow what a difference!!! This thing is unreal."

"Works great! Does exactly what it claims. My panels come out noticeably flatter than before."

"Purchased the Linear blocking tool and sand paper set as a gift. The quality is obvious the moment you hold it. Completely different feel from standard foam blocks."

"The polycarbonate body is incredibly rigid - no flex, no waves. I'll never go back to foam blocks. Best tool investment I've made in years."

"Backed by a lifetime warranty and made in the USA. Linear clearly stands behind their product. The results speak for themselves."
