Priming metal bases

I always spray prime my steel bases with a proper metal primer. Do peeps do anything when using coins? Had a discussion about PVA not sticking that well to bare coins?

I've never primed metal bases of any kind. In fact I've scraped the primer off the upper surface of those pre-primed metal bases because I don't like the idea of sticking anything onto a coat of primer.

I mix PVA with cheap filler for the first coat on my bases. That's never come off yet without some persuasion.

Just Halfords primer. Nothing fancy.

Use the same primer you use for your lead figures. This is because 1 and 2 pence coins, are made from copper plated steel and the coper coating has similar surface properties to lead, tin and their alloys.

Primers for ferrous metals, such as car primers, will not be as good as one designed for copper, lead, tin & aluminium.

I agree with EB about this:

I just use the standard primers. Black, grey or white depending on what i'm using it for and how I feel on the day :)
Sometimes...…..sometimes....I even use the red primer :o

My shinys are stuck on steel washers. I'm just undercoating in humbrol enamel as normal. Am I doing it wrong?
