Great Primer for Metal Surfaces!
I used the SEM 39683 Grey Self Etching Primer on a few metal parts that I was prepping for paint, and it worked fantastic. The spray goes on smooth and creates a great bonding surface for the top coat. I noticed an immediate improvement in how well the paint adhered, and the finish looks much more durable.The self-etching formula is a great feature, especially if you’re working with bare metal, as it helps prevent rust and provides a solid base for painting. The 15.5 oz can covered a good amount of surface area, and I didn’t need to apply multiple coats. It dries relatively quickly, which is always a plus when you’re trying to move on to the next step.
