Paint adherence etched brass (Moved by moderator)

[drmac]

I have been modeling for about 20 years.  I have not found a good way to get paint to adhere to etched brass.  Does any one have a suggestion.  

Thanks

Jack, I read a tip (on FineScale I think) that one person recommended - dip the items into blackening solution (quick dunk) - you do not need to need to blacken it, only to dull the patina of the etched brass.  They claimed this works very well - I have yet to try it?

 

cheers

p.s. I think this needs to be moved to the Painting forum

Jack, along the lines of the blackener, you could try dipping the brass in some dilute (1:1 or 2:1) white vinegar followed by a quick rinse in clear water. It should etch the brass enough to allow the paint to stick

Thanks very much I will give it a try.

My usual method: 

 

- lightly sand with 400 grit paper

- light coat of primer (either use Tamiya spray metal primer, or Admiralty paint on metal primer)

- paint with colour of your choice.

Sanding or dipping in white vinegar (mild acetic acid) will both do a good job of prepping the brass for a good primer, like Keith suggests. You still may end up retouching the paint after flexing the etch brass after attaching it to your model. Use a very fine brush fir that.
