1- Wash in Joy dishwashing liquid and warm water and then rinse:
2- Tracks covered with "Black4Tracks" (AFV Depot) for about 30 seconds:
3- Soak in Baking Soda (level teaspoon) mixed with a glass of warm water (30 minutes) this will neutralize the acids and then rinse and let dry.
Here's the results. "NO" or very small silver spots at best.
I then apply a coat of Burnt Sienna oil wash followed by a coat of Raw Umber oil wash to tone down the Sienna.
I don't work for Tankrat I just know it's a better product than "Blacken-It" for what I use it for. I understand that of late there has been a problem getting what was ordered from Tankrat but i've never had such problems and have always been satisfied with his service.
This was posted for what it is worth and in no way am I trying to sell you anything.
