Rust-Oleum Gray Paint Primer, 11 oz, 1 Piece 1 Pack Multi

I own a 3D printing business that I use this on all of my prints. it dries pretty fast and very even coverage. i never need to sand the print after spraying it unless absolutely necessary. It covers up any imperfections and hides layer lines in 3D print very well. The only con is that I wish you could get more out of the can; it goes a bit quick when you use it a lot. But over I highly recommend!

We go through so many cans of this! Before painting 3D printed helmets, we always use this brand! Out of 50 cans, we've had 1, not spray! Walmart fixed the issue, no problem!

This spray primer and gap filler works great for smoothing out 3D prints. It sprays easily and can be sanded and painted once dry. It really helps elevate the finish of craft projects.

Great product I use this in my props and 3d prints give great coverage wether it's in the sun drying or in the shop (with ventilation) highly recommend

Worked well with my steel wheels. After prepping the wheels by grinding and sanding the rust off, cleaning my wheels with a good cleaner and letting them dry, I used the primer. Filled in the light scratches, and sanded nicely. Be cognizant of the directions on the can, and read them. Top coat adhered well and looks great. Wheels are like new. Good stuff. Would buy again.

great for cars, projects and more! Hard to keep in stock!

It sprays very easily and it covers really well thank you !

paint did not spray like it should it spit a lot was low air pressure and didn't seem to fill anything it did spray on I would recommend regular primer

Im waiting for the class action law suit about this product. advertised as "automotive primer and filler", but you CAN NOT spray base paint urethane paint over this without blistering and cracking. 2 stage urethane paint has been industry standard automotive paint for nearly 30 years. i had to do a complete new paint job to undo the damage this primer caused

when I unpacked my groceries the primer was at the bottom of the box. the top was broken painted the inside of the bag half of the primer is used. I don't know what to say about this.
