Ballasting...A ghastly process made easy.....

[nachoman]

HAHA. That is about the exact same technique that I developed after trial and error. I never thought to share because I figured everyone did it that way - with their fingers!! You are right, it is a good method. The fingers spread the ballast easier than a brush. I still use a brush to gently sweep things into the right area, then use my fingers to finish things off.
