Painting brass
« on: August 06, 2018, 12:18:03 AM »
As memory no longer serves, I need to ask.

Is there a preferred paint for photo etched brass? Is there anything that can be done to the brass prior to painting that can help the paint adhere better?

Quite a while back now I scratch built some steps for a 1/48 Su27 UB. The handrails were brass wire and the paint (acrylic) simply flaked off at the slightest touch. In desperation I tried spraying the rails with Kleer (Future) first and this apparently did the trick as the paint is still as good as when I did it. I'm not advocating that it's a cure all just that it worked and has worked for me as a brass 'primer' since.

Hope that helps - Tug

As I said: Memory no longer serves.
Now that you mention it, I recall that trick. Thanks so much for reminding me.

The best way for painting brass is making sure that there is no grease (fingers :) ) anywhere on the metal. I usually put my brass models in a soda bath for a while, but that doesn't work for a plastic model with PE details. My avatar shows a brass railway model, but that's not a good comparison as it is a full metal model.

But to let any paint adhere better to the metal I spray brass always with a very thin coat of wash primer or etch primer. It adheres to the metal because of the slight etching quality of the primer. Car primers (Motip for instance) usually do their work as well, but I would never use that for a small model directly out of the spraying can.

The etch primer I use is from Phildie and leaves an extremely thin almost transparant coat without covering any details. On top of this primer you can use any type of paint and it will stay there.
Both types of primer (Phildie and MOTIP) won't cause any problem on the plastic parts of a polystyrene model.

regards,
Ivo
