Review: Nice primer for the money
Review: This is one of the best primers I've ever used in a spray can. It has great bonding to any surface material, awesome build up properties to level off those small scratches, is self leveling and Sands beautifully wet or dry. What I like about the black is you can see very easily where you missed sanding before you start painting. A lot easier than White or Grey primers to notice. I used it under a silver metallic on aluminum rims and it covered perfect. Consider I've also used 2K primer in a can and would take this over that whenever possible. Did an especially nice job on plastic to fill the deeper scratches. SEM makes a great product, worth every penny of extra money.

### ⭐⭐⭐⭐⭐ Review
*by D***G on 14 April 2026*

I tested 4 types of primer filler and this is the only brand that did not cause cure inhibition on the platinum-cure silicone molds. It works well in light coats and dries extremely fast. The consistency is good in light coats, this is important. Heavy coats cause the filler to foam and the finish will show small air bubbles when sanded. This only happens if the coat is sprayed on too fast and heavy.
