UNDERCOATING, PVC PAINTING AND RUST PREVENTIVE WAX TREATMENT Air dry a minimum of 4-6 hours [20°C (68OF)l. L Heat dry a minimum of 30-40 minutes [60°C (140°F)]. Color coat i Apply coating after PVC paint film is thoroughly dry. Sanding is not necessary if all oil and grease were completely removed. Conditions such as air pressure, paint viscosity, etc. can be same as for ordinary body coating. -1 Done in same way as for ordinary body coating. Nozzle type A Nozzle type B RUST PREVENTIVE WAX TREATMENT WAX APPLICATION PROCEDURE Preparation of equipment 1. Prepare equipment suitable for the wax chosen. 2. Use the correct nozzle, spray pattern, and in- jection pressure based on instructions provided for the wax. 3. If necessary, clean the nozzle with thinner before beginning work. Preparation of vehicle (or parts) 1. Scrape mud, etc. off the wax application area. 2. Dry any water collected at the wax application area. 3. The temperature of the vehicle body should be kept at more than 10°C (50°F) during the opera- tion. 4. Close all windows of the vehicle. Caution When repairing a damaged part, complete painting first, then apply the wax. The reasons are: a) The wax is sometimes dissolved by heat [more than 120°C (248OF)I during the drying process, resulting in deteriorated anticor- rosion effects. b)lf the wax applied before painting is smeared over the paint application surface, poor painting will result because the wax repels the paint.
