I hear alot about applying products to serve as a "light resist". I have tried using clear lac, and satin sheen and even tan-kote in the past to the entire leather piece prior to applying antique. When I applied the antique to the tooled areas, the antique seemed to not darken the leather, unless I left some of the paste in the tooled areas, using it as a paint. Using a coat of clear lac applied with wool seemed the worst, not allow any antique to penetrate the leather. This time I tried applying tan-kote to the leather, but using a blocking technique. I wrapped a piece of t- shirt around a small wooden block, applied tan-kote to the block and rubbed the block with the tan-kote on the leather. This applied my "light resist" to only the untooled areas. I was hoping this would allow the antique to penetrate into the leather better in the tooled areas, and not in the untooled areas. I applied my antique all over the piece, and removed it immediately using a block wrapped in cloth. This left the paste in the tooled areas, where it dried. I did this twice, leaving the paste to dry in the tooled areas. I then removed what was left of the paste with a cloth, but left some in the deep cracks. If I scratched it with my fingernail, the black antique paste that remained in the tooled areas would come off. The leather underneath has been darkened, but not to the level that I am hoping to achieve, which is black in the tooled areas, and mahogony/red in the untooled areas. I am using 6-7 ounce vegetable tanned leather from tandy. After tooling I applied one coat of neatsfoot oil with wool, and let it dry for a day. I then dyed the leather using fiebings alcohol based dyes by spraying with and airbrush. Then I perfomed the antiquing as described earlier. The piece looks like I want it to. So i guess i need to know if I should leave the piece as is and seal with tan-kote, assuming the antique is a paint like product. Or go back, try and remove whats left of the paste using deglazer, and put a couple more coats of antique on, removing all of the paste each time, until the leather has been actually died to the black color I need in the tooled areas. So I guess I am asking should the antique paste dye the leather in the same manner as a traditional dye would if I painted it into the tooled areas, or does the antique paste serve as a sort of paint, staying on top of the leather. I attached another photo of another piece I did using the same technique
