tection. A 10 mil wet film thickness is required to obtain
a minimum five mil dry film thickness. If needed, the
vehicle can be resprayed to reach proper thickness.
b. Spraying Pressure. The rustproofing compound
should be applied to sheet metal and structural
members in even coats. Spraying pressure should be as
low as possible while maintaining an even spray pattern.
An acceptable starting point is 40 psi (276 kPa), but
adjustments may have to be made due to temperature
changes and differences in rustproofing compound.
Using too much pressure will waste compound by
causing overspray and excessively thick coatings.
