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.
