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.

Paint adhered to the primer well. But the proper peeled up at a couple edges. Pretty sure I should have sanded them for better adhesion. My fault, not the products.

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

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.

Have used it on several projects. Always goes on smoothly and cover easily. Only complaint is that if you use a partial can. the nozzle may be clogged when you try to use the rest later.

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.

great product i had sanded some parts on under side of my project camaro 1973 rs.used this primer to seal from rust then appled raptor liner after it had cured

Works great so far. Uses it to cover stainless steel towel bars and toilet paper holder.
