## Customer Reviews

### ⭐⭐⭐⭐⭐ The best
*by J***. on June 15, 2025*

I use many different polyester primers. This one is more than double the cost, but worth every penny when doing a very high end refinish project. It’s surprisingly thin and transparent on first coat, but if you follow the manufacturer instructions, you will get fantastic results.

### ⭐⭐⭐⭐⭐ Must have this primer!
*by J***. on March 31, 2021*

This primer is the best for sealing a car. Its thick and it builds and fills as you block it. It will not shrink overtime. like other primers. I use 2 gallons on each classic car I paint.

### ⭐ Never received  product
*by W***S on September 29, 2024*

Expensive, never received it as of yet. Tracking info useless not updated. Recent response " wait till next week". At this point I would settle for a refund
