best way to detail tracks

The method that I use depends on if the track is an all steel track or one that has rubber pads.

For All Steel:
- Paint a base coat of Model Master Gun Metal
- Dry brush with Model Master Rust
- Dry brush with Model Master Steel
- Burnish with ground pencil lead
- Dust with pastel chalks with the rest of the model

For Tracks With Rubber Pads:
- Paint a base coat of Tamiya Flat Black
- Dry brush end connectors with Model Master Rust
- Dry brush end connectors with Model Master Steel
- Burnish end connectors with ground pencil lead
- Dust with pastel chalks with the rest of model

The way that I do my tracks is: Give a coat of flat black with a bit of gunmetal mixed in (if airbrushing) I will let them dry for at least 12 hours (especially if they are the flexible ones) Once fully dry, use Steel color in drybrush technique and give a coat of flat or matte to protect. The best way to do all this, for the flexible tracks, is to masking tape the ends to a long piece of cardboard.

I don't add any rust or mud color to mine until they are finally on the armor itself.
