A really well scaled blend that accurately reflects prototype size. The Grey mix colour has been chosen based on field research and does include a small addition of lighter and darker stones as granite ballast often includes more crystalline or darker impurities. It is suitable for newer ballast, lightly used modern or new Steam Era lines in some areas.
Use in combination with other Legacy Ballast for transitional areas and weather with powders or paint as appropriate for realism.
This carefully processed Ballast should not change tone when glue is applied using a suitable mix and wetting agent.
