Any tips for painting metallics over other metallics?

[StrangeGuy]

I have decided to paint up an Auric Patricians army. Their colour scheme is mostly gold, so I bought some retributor gold spray to base coat my models with. I've started painting up my first test mini, and I'm finding that the gold is coming through the Leadbelcher I'm trying to paint onto the model's bolt rifle. Other than applying multiple coats until I get the coverage I want, is there anything I could be doing to make life easier for myself? Thanks in advance.

The areas that your going to paint Leadbelcher, paint it black first.  Are you watering down or thinning your paint?  Any bottle of leadbelcher I've had is pretty thick.  But paint all your areas black first then your next metallic color

Thanks for the response. I am thinning my paints, I thought maybe I just needed to do a couple layers because of this but even after two layers the gold was pretty noticeable. The black idea is a good one, and will be really easy to do once I get done with these snap fit test minis and move onto multi-part kits. Seems kind of obvious now that it's pointed out.Thanks again!

Not everyone cares about being cheap but Retributor Armor and Leadbelcher sprays are offensively expensive, I'd be tempted to spray the model black and just brush on the gold which has really strong coverage. I brushed Retributor over Leadbelcher on my AT titans and it went on really fast. 

 

I've always found Leadbelcher pretty opaque but I thin it so it's not really clumpy.  Two coats is all I've needed to cover almost anything, is the paint kinda wicking around on you over the gold?  I've found metallic sprays sometimes have a weird surface depending on spray conditions where I've had a hard time getting other colors to stick on there without acting hydrophobic.  You also might thin the Leadbelcher with medium instead of water, it can act a little better if your surface seems hydrophobic in spots.
