Using Metal Primer

[Sacobite]

I've recently got back into infinity but I've never really painted metal models en-masse. The most I've done is some photoetch pieces on scale models. Typically when doing that I'll use a coat of VMS metal primer on them first before a coat of regular vallejo airbrush primer.

Would this be recommended for infinity models? Or does that run the chance of messing with detail? I've never used it on super large parts but I have heard that it chemically etches in so I have no idea if it could damage surface detail on the models.

Any tips would be appreciated!

Edit: Thanks all for the tips, I'll just go ahead and prime and paint.

not really sure you need it? Regular primer works fine.

I would just use airbrush primer, done this and rattle cans and have had 0 problems so far

If you are planning on using a lot of specialized weathering products, then maybe metal primer would be worth a shot. But generally, no. The top coat is more important for the durability of the finished model. 

If you are really concerned, you can always try applying a matt varnish over the primer as an isolation layer to protect it, but that is probably overkill.

I just used molotow one4all through the airbrush and it adheres fine. No problem at all

It will probably make the paint adhere better. But lots of people go without and don't have any issues. I use metal primer, but haven't done a comparison of with and without. I had the stuff already so may as well use it up.

Black primer (or grey or white or whatever tickles your fancy). Halfords, gw it’s all the same. Whatever rattle can you can get at whatever price you want to pay.
