Before masking up, or any paint is applied, this is your one last chance to check repaired surfaces, etc., for anything that has been missed. Remember that paint will not hide or fill bad repairs, if anything it will make them look worse!
The following steps presume the paint mixture is prepared as directed by the manufacture, with the correct thinners and activators in the correct amounts. Final filtering of the mixture as it is put in the spraygun is recommended using disposable paper filters
If you are new to spraying, regardless of whether the paint is to be applied with an aerosol or a spraygun, practice on some other surface before putting paint on carefully prepared panels. Everybody will get runs, sags, stripes and dry spots at first until they get the basic skills required. This applies to professional spray equipment as well, which just gives you the ability to paint bigger areas badly!
If a full panel is to be painted, start at the top edge applying paint in evenly spaced strokes from one side of the panel to the other without pausing. Start the flow of paint onto the panel just before the starting edge and stop the flow of paint just after the finishing edge. By doing this the spray applicator is already moving as the paint is applied, so there is less chance of a sudden build-up of paint at the start of the panel. This is known as "triggering" when using a professional type of gun. The next stroke is taken immediately in the opposite direction, overlapping the first just sufficiently so that there is no "dry spray" gap left between the two. The amount of overlap will depend on your spray equipment , the more powerful types covering larger areas with each stroke whilst allowing smaller overlaps. >>>Continued
