Brass Channels.
Use these square brass channels for architectural model making, engineering, frame building, model railway, dioramas and other scratch building projects.
Brass forms a greyish-green layer on the surface, which you should remove (sand, polish) before soldering. After polishing, to preserve the shine, apply a clear laquer to the surface.
Our Workshop staff use Hycote Clear Gloss on their brass etching work.
