U-POLAcid#8 - Etch Primer M.I.R. Compliant

Covers good nice spray pattern

I've used a number of cans of this primer and really love it. I typically use it with a lever type spray handle for more control. You just have to be careful and not hold the can over the piece that your spraying. I would buy quarts to spray with my HVLP guns if I could get the product.

Great etching primer sprays nice an great coverage for medum size areas where you dont want to use acids . Paint adhears good an no problems .

Great for small projects. Not much in a can.

I love this stuff, it lays down real nice, it dries quickly, and the topcoat of paint flows super nice for a beautiful finish. I won't use anything else.

I bought my can in Sept of 2015- now summer of 2019 I’ve pulled it off the shelf and started to use it. It had been through all sorts of weather including freezing and hot summers. I’m impressed enough by its use and quality to come back and buy another. I had zero issues with the tip, so I can’t comment on what all the complaints are about.

Used to etch a diamond cut aluminum tool box before spraying with Rhino Liner. Bond feels great. Will update if there are any issues after a year or two.

After a third party recommendation, I have been using this product to restore a number of outdoor light fixtures as well as a collection of other metallic objects. After scrubbing the objects and removing excess quantities of rust, I apply the spray to, allegedly, promote protection of the metallic surface as well as boost paint adhesion. While I’m merely a DIY-er, with little more than average understanding, the aerosol spray performs perfectly. The final paint coats adhere soundly and, to my own surprise each and every time, lead to a pristine-looking object. So, without the technical background and arguments, this product works for me.
