This new blackening gel makes it easy to achieve uniform, tightly adherent black finishes on surfaces of any size and shape and offers the user an extra measure of control over the finishing of the workpiece. The unique gel consistency makes it possible to overcome many common application challenges, such as achieving uniform applications, controlling runs \u0026amp; drips, minimizing solution loss due to runoff and inhibiting flash rusting of the surface. The gel stays on the part with no loss of product due to runoff, and leaves an invisible protective film on the surface to inhibit flash rusting during drying. Even works on vertical surfaces!

This new gel makes it easy to achieve uniform, tightly adherent brown finishes on surfaces of any size and shape and offers the user an extra measure of control over the finishing of the workpiece. The unique gel consistency makes it possible to overcome many common application challenges, such as achieving uniform applications, controlling runs \u0026amp; drips, minimizing solution loss due to runoff and inhibiting flash rusting of the surface. The gel stays on the part with no loss of product due to runoff, and leaves an invisible protective film on the surface to inhibit discoloration and water-staining during drying. Even works on vertical surfaces! In short, the ANTIQUE BROWN GEL simplifies the entire coating operation and improves the quality of the final finish.\u003c\/p\u003e\r\n\u003ch1\u003e\u003cu\u003eAPPLICATION INSTRUCTIONS\u003c\/u\u003e\u003c\/h1\u003e\r\n\u003cp\u003eTo obtain best results, please use the following procedure:\u003c\/p\u003e\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003col\u003e\r\n\u003cli\u003eStep 1: CLEAN THE SURFACE to remove any extraneous oils, oxides or other soils that are present. Tarnish, soldering flux and other oxides are best removed by bead blasting or other abrasive cleaning methods. Oils can be removed by wiping or scrubbing the surface with solvent cleaners. Use a clean solvent that evaporates without leaving a residue, such as alcohol, acetone, MEK. Do not use Mineral Spirits; it leaves a residue on the surface. Scrubbing the surface with SCOTCHBRITE pads (from 3M Co.) works very well to remove surface soils. The objective here is to achieve a surface that is free of oil and oxide and in a uniformly reactive condition.\u003c\/li\u003e\r\n\u003cli\u003eStep 2: RINSE WITH WATER, if necessary, to remove any cleaner residues and achieve a water-break free surface. Note: Rinsing is usually not necessary after solvent cleaning.\u003c\/li\u003e\r\n\u003cli\u003eStep 3: BROWN THE SURFACE by applying a liberal, uniform layer of ANTIQUE BROWN GEL with a synthetic brush or swab. Allow to react for 1-10 minutes while lightly brushing the surface with the applicator until the desired depth of brown color is achieved. By controlling the contact time, colors from golden brown to chocolate brown can be achieved.\u003c\/li\u003e\r\n\u003cli\u003eStep 4: RINSE WITH WATER to remove any browning gel residues.
