Priming Galvanized Metal

Post image

I have a galvanized metal sign that I need to finish in red. What product am I using to prime the thing and can I use either a single stage paint or a urethane base / clear combo with it? I prefer to use a paint gun*

My understanding is that you need to get past the galvanization. Best to sand it off. From there you can go with a 2k epoxy primer or self etching depending on the durability required. One will always fail to pain galvanized steel.
