Birchwood Casey Presto Black Gel Patina - For blackening/antiquing of decorative steel surfaces without runs and drips. Unique gel formula has a slower reaction than BST4 Liquid, giving the user an extra measure of control when dealing with large surfaces. Gray/Black finish. Presto Black Gel- Designed for use on any size part in limited quantities, the new Gel solves the application challenges of liquid products while producing an attractive, high quality, durable black finish. PRESTO BLACK GEL simplifies the metal blackening operation. After cleaning the part surface in the normal manner to remove cutting oils, coolants, etc., the user simply swabs on a layer of PRESTO BLACK GEL with a synthetic paint brush. Then allows the Gel to work for two to ten minutes. The Gel adheres to the metal surface and blackens uniformly without running off ��� even on vertical surfaces. With most parts, no re-application of the Gel is necessary. When the desired depth of black is achieved, the Gel is simply rinsed off in the normal manner, leaving behind an invisible protective finish which inhibits water-spotting and corrosion during drying. The resultant black finish is clean and tightly bonded to the metal substrate, and can be sealed with BIRCHWOOD CASEY DRI TOUCH PLUS IRP3 non-tacky rust preventive for maximum service life. Ideal for finishing prototype and short run metal fabricated parts, PRESTO BLACK GEL can be used for blackening sharpened cutting tools, for molds, dies and on previously blackened parts that have been re-machined. The PRESTO BLACK GEL also works well on platens, machine tables and fixturing devices that require re-blackening as part of maintenance or overhaul. This re-blackening can be done without disassembly of components when necessary. NEW PRESTO BLACK GEL provides a new, more efficient finishing option to manufacturers using immersion or brush-on finishing processes. While immersion tank lines are most economical in production-scale operations and brush-on techniques prevail in shops dealing with large workpieces and small part quantities, the PRESTO BLACK GEL process provides both of these manufacturers with a faster, cleaner and more cost-effective alternative. Large workpieces using liquid blackeners, for example, are challenging to work with due to difficulties of applying the liquid to a large surface uniformly. Another problem is minimizing the runs and drips during the finishing cycle and re-applying the liquid where needed to carry the blackening process to completion. Following blackening, these workpieces need careful rinsing and drying to avoid any tendency to waterspot or corrode. Each of these steps can reduce the level of operator control needed to achieve satisfactory results. By contrast, the new PRESTO BLACK GEL simplifies the process and eliminates most of these problems.
