Recommend a Primer

Can anyone recommend a primer that is suitable for kits made up of white metal, brass and resin parts. Don't know if it makes a difference but the top coats of paint will be acrylic.

Thanks

John

Halford's do excellent primers - normal, etched, filling and plastic varieties so you should find one that suits :)

Thanks for the replies.

Not sure I made it clear in the first post but this is a single kit made up of white metal, brass and resin parts.

I assume that an etched primer would be best?

I've used Halford's normal grey/white/red primer on mixed media projects with success. As long as the parts are clean it goes on really well.

I have made kits in all those materials. I don't prime the resin ones and have never used an etch primer. I don't prime very small models either, in any material, for example bicycles or hand carts. The Halford's grey primer works very well for all else.

What is important is to wash and clean the model before you do any painting. After washing, I put mine under a plastic cloche to keep dust off and let them dry.

For brass use an etch primer. PPP do good one, if you have an airbrush.

Halfords also do an excellent etch primer called U-POL Acid #8 Etch Primer in a rattle can.
Yes, expensive at around £16, but sticks like the proverbial, and gives a super fine finish too.

I've had excellent results using Halford's U-POL Acid #8 Etch Primer, but always on brass. I don't know how it would work on white metal and resin - would it then act as a normal grey primer or would it be pretty useless?

Thanks for all the replies, looks like a trip to Halfords is in order.

Just an extra note on the U-Pol primer, should be available from motor factors that sell paint as well as Halfords. May be worth comparing prices.

This is Halford's own etch primer -

For mixed media it sounds like a decent punt from the blurb.

To throw a cat amongst the pigeons.... I'm currently trialling an automotive sector 2k primer. This is not cheap but sprays very thinned down so takes a number of passes, but so far very good coverage (albeit built up), no damage to either a Hornby or Bachmann body shell and a bomb-proof, very smooth, thin coat. I've also used Halfords "acrylic" primer thinned with IPA to reasonable success. It is also worth tapping their paint desk people for straight automotive acrylic coloured paints - the black is nuke proof, goes on well too - and if you get thme in a good mood available in a tester pot for about £5/110ml (they're supposed to sell a litre at £25, but as i required a small a mount and there was no mixing they were lenient).

There appears to be two camps here - one that does not use an etch primer and one that does.

With developments in paint technology in recent years, is there any advantage in using an etch primer and if so, what is it?

Etching primer does what it says, it etches/attaches itself to the surface providing a good key for the top coat to adhere to. Halfords plastic primer can be used without fear on an all metal construction model and will give a satisfactory finish to a top coat. An etched primer - in my experience - gives a better finish. Let me qualify that by saying I only spray top coats using cellulose paints, I do not use enamel or acrylics for top coats/finishes. I've found cellulose gives a far better gloss finish than either of the other two. Cellulose can be sprayed over the top of Halfords plastic primer without problem. Just remember that what ever primer you use, your model has to be spotlessly clean, no primer will hide problems only exaggerate them.
