U-POLACID#8 Acid Etch Primer, Automotive Etching Primer Paint For Bare Metals, Durable Against Rust & Corrosion, Easy-To-Use, Gray, 1L

Seems to be a Great product as with any coating time will tell. I shot this out of a 1.5 and it laid down great. Degreased then primed these awnings and finished with raptor spray in bedliner. Will use again.

I used Acid 8 on several fabrication projects where bare steel is welded and sanded. I cleaned with lacquer thinner and sprayed Acid 8 followed by Raptor Bed Liner spray. Never had any issues with adhesion and the finished project looks great. Some projects are 3 years old and stored outside in the North East with no rust.

Works

Put bedliner on deck of aluminum boat. This primer gave me perfect basecoat for spray-on bedliner.

used on 3/16" armor skid plates for my OHV. used a grinder to remove surface rust, cleaned with drug-store isopropyl, applied 1 coat of this primer with a cheap paint brush, let dry 1 day, painted with Raptor Liner, let dry for 3 days ... 6 months later, no rust, no raptor liner flaking ... great product

This is not a review of the product itself because I only just received and have not been able to try it out. Shipping box was fine but the paint can damage is awful. Why would this be cleared to ship in the first place?

Quick easy use acid etch and easy to use lays smooth dries great.

This etch primer worked very well as a base for raptor liner spray. I touched up some areas with rattle can primer and had much poorer results.
