Nice primer for the money

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.

This primer is EXCELLENT! I use it to prime small metal parts in my auto restoration shop. It has a high build quality and is easy to sand. It dries quickly and the coverage is great! Buy this product!!

The primer is very good; dries quickly covers and fills well, sands well. Unfortunately, 2/3 cans I purchased I couldn't use as the nozzles kept clogging. I kept cleaning them but would get barely 1-2 seconds of spray before they blocked again. I tried swapping nozzles thinking maybe it was just a nozzle issue but it was not. The other can I used completely with no nozzle blockage. Ended up having to use a different primer that I picked up locally which wasn't as good but it did come out of the can to finish the job.
