Hello all, know this has probably been discussed before as a few Q's need answers. Unable to darken bbl's while not showing pattern. Have a set of damascus Parker bbl's of which are going through a browning process using ML browning solution. After the 320 polish bbl's were initially submerged in 12.5% etching solution for 5-7 seconds then rinsed, carded in distilled H2O. Browning solution applied 2-3 rustings then wet carded/0000 steel wool after yellow rust appeared. Then etched and process repeated. Again, etched after 2-3 coats of rustings. Bbl's are on the 14th cycle and remain with a faint brown patina and no contrast. Any advice appreciated.
