## Description

Universal 2K epoxy primer filler for all problematic surfaces; for example, metal, non-ferrous metal, galvanized sheet steel, or anodized aluminum. Warning: This product can expose you to chemicals which is [are] known to the State of California to cause cancer and birth defects or other reproductive harm.

Review: As advertised. Worked great, very durable. It left a heavy texture but was easy enough to sand out to prep for the next coat. My only problem is with the cap. I inverted the can to activate the hardener as instructed, but the lid exploded when I pushed on the bottom. I had to activate the hardener with a screwdriver.
Review: I needed an epoxy primer to use on another aluminum stern drive on a boat between the etching primer and the color coat. The last time I did this on a different stern drive I used Alodine, this 2-part epoxy primer, topped with acrylic enamel 1-step paint. It held up well in freshwater boating, but it was apparent that I should have used a better color coat due to some staining. For this project, I used a zinc phosphate etching primer, then this 2-part epoxy primer, then an acrylic lacquer color coat, then an acrylic lacquer clear coat. Every coat was compatible with the previous coat. This stuck well to the zinc phosphate layer, and most importantly, the acrylic lacquer stuck well and had no issues being applied to this 2 part epoxy primer. For those who know paint technology, you realize that selecting the proper kind of coating to keep from having the acrylic lacquer burn through the previous coating and ruin the job is of utmost importance. This 2-part epoxy primer is more than up to the task. Just be sure to follow the directions and apply the color coat between 15 minutes and 12 hours after applying this product. While I do have professional paint application equipment, for smaller jobs like this I prefer to use a quality rattle can process. Without this product, that would not be attainable. Just be sure to understand that the nozzle is adjustable, and it will not be set the way you need it to be set right out of the box.

**Q: Can this be used as a sealer after an adhesion promotor, when prepping for raw plastic bumper?**
A: not needed for plastic. there are better products out there to use on plastic parts

**Q: How do you activate ? I am not a painter. Thanks.**
A: Remove the red cap from the lid and place it on the bottom of the can to puncture the mixing agent. You can Google it.

A: the one i received was grey

**Q: Sooo... I forgot to activate it and used this product during a repair.  How successful will it be at doing its job?**
A: The activator is the hardner. Without this I would be afraid to paint over. Soft primer will lift. Remove the primer and respray with activated primer can.
