OK I told everyone I was going to try "Black4Tracks" from TankRats AFVdepot on my Friuls instead of "Blacken It" this time. I've used Blacken It on five sets of tracks and each time after a long soak,tooth brushing and every degreaser known to me the tracks were always covered with silver spots on the detail side. I would cover these with heavy applications of umber oil washes. It was no big deal it just took a lot of extra drying time between coats.
Then a new product hits the market and I figured what the heck nothing ventured nothing gained so I ordered a bottle. The tracks for the Hummel would be a good test because of the very small details deep down inbetween the treads. So without farther ado lets do it.
Tank Rat told me to just degrease with a dish washing liquid like Joy,no reason to get exotic so I did just that and I also used my old tooth brush to scrub them down front and back,rinsed and used the wife hair drier until good and dry.
Useing a small container I poured all but about an ounce over the tracks and swished it around a little. After they begain to blacken I took them out and placed them on that blue lid you saw earlier. I dipped my tooth brush in the solution and scrubbed them down again front and back to make sure all the details were exposed to the Black4Track and put them back in the container for an another minute or so.
To stop the chemical reaction and neutralize the acid I mixed a teaspoon of baking soda in a glass of water in advance so it would be ready and soaked the tracks in it for a few minutes. Did the tooth brush routine and then rinsed the tracks in running water. Hair drier time again till dry.
And here are the results after maybe thirty to forty five minutes total woking time. There are a few silver spot in the deep and very small detail but nothing that a normal oil wash won't cover with one coat.
Tank Rat you've made a believer out of me your "Black4Tracks" at least for me,is a much better product for the job it does on FriulModel tracks.
This review or test was not solicited by Tank Rat or his company and i've not received any compensation nor do I expect any.
Now I can finish in a day what used to take three or four. Tony the Mutt
