For best results, diluted BONDERITE^® L-GP PRODAG should be applied via conventional spray techniques. BONDERITE^® L-GP PRODAG can also be brushed, however spraying ensures a more uniform coating and helps prevent mold build-up. The recommended starting dilution is at least 1:4 (BONDERITE^® L-GP PRODAG:water), but dilutions of 1:10 or higher are normal during production. The concentrate should be agitated before and during dilution, and the diluted product should be stirred during use to keep the graphite dispersed. The mold surface should be clean and pre-heated to at least 200°F (93°C) prior to being coated to ensure fast evaporation of the lubricant and good film formation.
