-
Undercoating should be applied after the welding and refinishing process. Product cannot be welded through.
-
Air pressure setting for applicator gun is 552 kPa (80.06 psi) – 621 kPa (90.07 psi).
-
Apply light mist coats, applicator sprays in fogging pattern. Material displaces moisture.
-
Clean up any overspray with a mild solvent such as mineral spirits or bug and tar remover.
-
NOTE:
Frame rail exterior spot-weld flange view.
Apply Premium Undercoating material to the exterior
exposed edges after carrying out the welding and refinishing process.
