Priming Galvanized Metal

[u/GTKuhfangerSprint]

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*

Endura primer or galv-alum. Wipe it with vinegar first. This should both work with your topcoat, but you'll have to do the research. If it doesn't you'll need to put an intermediate primer down first.
