This is the new epoxy primer I have been using after the zinc chromate era.

I bought it at a company on the lelystad airport in the netherlands.

It's pretty expensive stuff and apparently it seems to be the same primer used on the latest Airbusses these days.

It comes with Hardner and Thinner to control the viscosity. Great stuff, but as said, pretty expensive and not possible to buy small quantities. You have to buy it per 10L so I'm lucky that my fellow builder Hugo is using the same.
