hmmm just looked up that foliatec interior colur spray and it says:

"Foliatec Interior Colour Spray is suitable for hard plastics. Such as, door cards and heater vent surrounds. The colour spray is step 2 of the process. First you must clean the surface thoroughly and we recommend the use of Foliatec Interior Cleaner.

The foam cleaner will remove any dirt and/or grease from the surface before you apply the colour.

Then to protect your coloured finish, it's time for step 3. A clear layer of sealer. Interior Sealer Spray.

Leave several hours between applying 2-3 layers of both colour spray and sealer spray."

so according to that other than cleaning what i want to spray i need not do any other prep work?
