Dust contamination are commonly known as dirt in the car paint’s finish, in fact, foreign particles have been set in in the paint film.
There are several reasons behind the dust pollution problem of any car painting job. It includes a dirty and dusty environment used for the spraying process, unfiltered air enter into the spraying booth or poor air filtration, the use of a substandard masking paper are also the reason. In addition, if used an unclean spray gun, then it is also possible to happen dust contamination.
So we should keep our work area and spray equipment clean, we should completely blow off around the doors, windows, jambs, moldings, wheel openings, trunk, engine compartment and hood. All the surfaces that need to be painted as well as the masking paper should also be wiped off with the use of a tack rag. Masking materials should all be of high quality or else you might find your paint job contaminated with wicks from newspapers, which tend to break off and blow right into your wet paint.
