Self Etching
I was looking for a good self etching aluminum primer. This primer works very well and it sprays on really good. It has excellent adhesion.

Nice paint
Bought two colors black and gray so can paint two colors to get solid coats in between with no misses. Three coats total on my utility trailer.

Used for aluminum boat did wonders! 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.

Great product
Worked great on my frame! Used to primer the frame of my Jeep during frame-off restoration. Painting over it with raptor liner. Covers smooth and clean. Dries quickly and etches how it should. Def recommend
