The customer used over 32 gallons (120 L) of Tectyl paraffin inhibitor in the entire bus skeleton. This required the placement of 1200 quarter inch (6mm) holes throughout the chassis. A labor force of 18 men was required to drill holes and plug them after Tectyl was applied.
The alternative method was to eliminate 75-80% of all holes, apply VpCI®-309 powder, plug the holes and cap/seal ends of tubes of the frame, while seeking to maintain the manufacturer’s 12 year rust free warranty.
As a result, the customer eliminated fire hazard, spillage, and the lost time required to drill holes and plug holes.
