The TRU TEMP finish is said to protect tool surfaces of all types, including wrenches, sockets, pliers, screwdrivers, chisels, etc. with a non-dimensional deposit that does not interfere with the function of the tool. The process provides branded hand tools with a deep black, protective finish that resists rust and also displays well in retail packaging. The process is said to take just 25 minutes of processing time with a chemical cost of $.01-.02 per pound of finished work. Small parts can be processed in bulk loads, larger parts in baskets or on racks. Most existing tank lines can be retrofitted at low cost to accommodate the process, or new tank lines are available from the company in all sizes.
