@BillGorm – Bill,
First, sorry for posting this so late this evening but had some unexpected things get in the way, as usual!
Anyhow, I can’t see any of the photographs at work due to the firewall so I couldn’t comment on the tracks – but now that I'm here at home, they look excellent and ready for some weathering. Your method is exactly the same method I use for getting these tracks to look somewhat aged. To get them to come out darker using the Blacken-it solution I first leave the metal tracks soaking in vinegar overnight in a plastic container (cleaned out cottage cheese container). After which I dunk them in a light solution of baking soda and then rinse them with warm water followed by a blow dry. That will usually get them to come out darker. To get them even darker you will have to soak them in a second solution of Blacken-it. I only darken the tracks if I want to depict a less worn or weathered vehicle.
As your tracks sit I give them a diluted wash of oil paint (90% Oderless Turpenoid to 10% oil paint) – mixing browns with black to both sides of the track faces. You could then follow this with varying shades of light to dark browns randomly washing every other link on the road wheel side of the tracks. After allowing them to dry overnight you could go over them one more time but only on every other third or forth link. Depending on how much contrast you want you could also increase the percentage of oil paint to Turpenoid. I then go over this with a single wash of Rustall – German tracks don’t show hardly any rust if any at all so this is just to give them some oxidation before the pigments are applied.
Bill, here is a link that you may find of interest for the
over painting of tools with another link on that same post with more information. And more
over painting of tools. Some of the photographs are missing but I think you and others here interested will understand what’s being conveyed. And something new to use as a substitute for the
hairspray on future builds that you may also fine of interest, I did!
Hope this is of some use and help for you,
~ Eddy
