Would buy again! - Used to prime a aluminum boat and it worked perfectly! I would definently but again. I was well impressed at the quality and ease of use. You still need to prep before but it makes a solid base coat that clings to the metal. I’ve already covered the boat in Berliner but the seats still need painting and are the primer sprayed on. Review: Worth the money - Sprays well. Lays out flat. ## Features - 1 Gallon (3.8 Liters) Can of Custom Shop Premium Self-Etching Acid Etch Primer. Black primer color.

Would buy again! *by M***K on July 29, 2020* Used to prime a aluminum boat and it worked perfectly! I would definently but again. I was well impressed at the quality and ease of use. You still need to prep before but it makes a solid base coat that clings to the metal. I’ve already covered the boat in Berliner but the seats still need painting and are the primer sprayed on. ### ⭐⭐⭐⭐⭐ Worth the money *by T***T on June 20, 2026* Sprays well. Lays out flat. ### ⭐⭐⭐⭐⭐ CRAZY GLUE OF ACID ETCH PAINT *by B***E on August 15, 2026* Let me tell you. This stuff is amazing. I have a project jon boat. I have used other products in the past that didnt cover well, stick after meticulous prep work or didnt last. This stuff is crazy glue of paint for bare aluminum and old galvinized metal trailer. Used an automotive spray gun to apply 2 coats. First coat covered everything. Dried to touch in about 15 mins. Applied a second coat at about and hour. Lays flat, and smooth. I highly recommend not using any other product.
