1. Ensure the vehicle is at paint shop temperature to avoid the condensation that occurs on a steel body shell if brought in from outside.

Merely wiping with Spirit wipe (petrol) will not pick up moisture – the petrol repels it from the cloth.

2. Make sure the surface is clean and free from flatting sludge, oily deposits or hand marks.

3. Use Etch Primer on bare metal, followed as soon as possible by the full undercoat and colour coat system.

4. Use sufficient undercoat and colour coat. Two thou" of each when applied as per process sheet.

5. Use quality thinner. viz - 396 for RPFTOO and 800 and appropriate thinner for colour coats.

Cheap thinners often contain large quantities of solvents that themselves contain water. eg. Acetone and Alcohols. Cheap thinners can also cause precipitation of the resin (or binder) system in cellulose products, particularly in cold and damp conditions. This precipitation weakens the adhesion and allows blisters to form.

6. Allow the paint to dry out well, in good ventilation, before putting outside. ie. overnight for air dry materials. Low Bake paints are not so prone to blistering.

7. Do not use paraffin heathers, These create water vapour during combustion, thus creating conditions of high humidity.

8. Avoid prolonged exposure of new paintwork to very wet Conditions.

Vehicles should go into service as soon as possible after the specified drying period. The road movement prevents the water from standing on.

9. Do not wax polish new paintwork. This can trap residual solvents which pick up moisture.

10. Drain down the air pipes regularly. Condensation in the air lines can cause moisture to be deposited with the paint when spraying.
