Rust-Oleum 249322 Automotive Self Etching Primer Spray, 12 oz, Matte Dark Green

This worked very well for my application. I painted a hitch coupler that I welded up from bare metal. The primer was easy to apply evenly and made for a good looking top coat. It has held up impressively being used on an ATV trailer frequently towed over gravel roads.

Adheres well to metal, couple of thin coats and a wet coat, flawless.

One of the best brand products on the market you can’t go wrong when you buy this one it works good

Very good quality

Lot easier than loading a gun

I had aluminum chairs that I had to prime to get the paint to stick. I tried paint made for grills. Didn’t work. I needed two cans. Same product at the home improvement store was $2.50 more per can. Saved 5 bucks. So far the primer worked on the aluminum chairs. The new paint isn’t flaking off the primer. Chairs look new again.

Some surfaces are coated with a rust and corrosion inhibitor, or is alluminum or other surface. This product helps to bind with the substrate. I use it as it is as its a grey, or greenish that matches a lot of things. Or a topcoat and it holds up well. I mean Rustoleum holds up well anyway in my experience but this adds another bond. The green product does not say automotive. Pretty much the same other than that! Not sure how this works on plastic, however rustoluem has another product just for alluminum.

So far, seems to be good paint
