No. It has very good corrosion resistance without the zinc or aluminum is the better product.That's nice!
Does the Jotun 80 have zinc in it? I need something with very good corrosion resistance.
Here’s my 2cents worth with zinc and aluminum epoxy primers. Galvanising works as the zinc is a sacrificial coating, not sure you want a sacrificial substance in your car paint. Adding zinc and aluminum means you’re adding products that don’t adhere so typically they are not as surface tolerant and will be more prone to chipping. If they chip then the area is exposed and will rust. If the zinc and aluminum aren’t all connected does it actually act like galvanizing?
