b.
Reduce basecoat per label directions. Some activated Polyurethane Enamel materials are ready to spray as packaged under normal conditions. As
conditions vary, to enhance flow out and leveling up to 10% more than the specified enamel reducer may be added to the activated mixture. Check
the viscosity of the activated mixture with a Zahn #2 Paint Viscosity Cup or its equivalent. Follow the paint manufacturer's labeled
recommendations for paint viscosity cup reading.
c.
Using manufacturers specified air pressure at the gun, spray two medium-wet coats of enamel mixture to achieve full hiding. Allow first coat to
set-up for 15-20 minutes before applying the second final coat. Unless manufacturer recommends otherwise allow to cure overnight.
7B. Lacquer Basecoat
a.
Reduce base color 150-200% with an extra-slow drying lacquer solvent. The viscosity of the reduced base color is very important in order to
match the OEM (original equipment manufacturers) finish. The best
way of checking the viscosity of a reduced paint material is with a Zahn #2 paint viscosity cup or equivalent. If a cold can of paint is brought into an
average temperature room (65-70~), it will be thicker and more viscous. Adding solvent to make the paint sprayable is not the best action. The paint
should be allowed to reach workable, or average room termperatures. Follow manufacturer's recommended paint viscosity cup reading for their
material.
b.
Spray base color at 35-45 lbs. air pressure at the gun or as specified by the paint supplier. Apply only the number of coats needed to get full
hiding. This will require two or three medium-wet coats. Allow each coat to flash approximately five minutes and spray each coat slightly wider
than the previously applied coat. A premixed mist coat of clear acrylic paint material may be used if desired to melt overspray into the base color.
Allow to dry for 20 minutes before applying clear coat. Do not sand base color coat unless it is necessary.
8.
If basecoat must be sanded, proceed as follows:
a.
Allow base color to dry.
b.
Sand with ultra-fine wet-or-dry sandpaper to remove the imperfection(s).
c.
Reclean and tack wipe the repair area(s).
d.
Apply an additional coat of base color.
e.
Allow to dry 20 minutes before applying the clear coat.
9A. Polyurethane Enamel Clearcoat
Because of the better durability of polyurethane enamel clear costs as compared to lacquer, it is preferred if shop conditions allow.
CAUTION: There are a number of paint systems available for service use: however, may require additives containing isocyanates. It is essential that all
recommendations and warnings listed on the container label for materials selected be followed.
It is mandatory that adequate respiratory protection be worn.
Examples of such protection are:
3-M Models #6984 and #6986 disposable respirators.
Such protection should be worn during the entire painting process. Persons with respiratory problems, or those allergic to isocyantes must
not be exposed to isocyanate vapors or spray mist.
a.
Following paint manufacturers' label directions, activate the Polyurethan Enamel material. Mix material thoroughly. Pot life of
activated mixture is approximately eight (8) hours.
b.
Reduce basecoat per label directions. Some activated Polyurethane Enamel materials are ready to spray as packaged under
normal conditions. As conditions vary, to enhance flow out and leveling up to 10% more than the specified enamel reducer may
be added to the activated mixture. Check the viscosity of the activated mixture with a Zahn #2 Paint Viscosity Cup or its
equivalent. Follow the paint manufacturer's labeled recommendations for paint viscosity cup reading.
c.
Using 50 lbs. air presure at the gun, spray two medium-wet coats of enamel clear coat mixture. Allow first coat to set-up for
15-20 minutes before applying the second final coat. Clear coat should be applied over the entire panel wherever possible.
When no breaklines are present blend all spray applications within the adhesion promoter boundry (Figure 1) .
Clean spray painting equipment with lacquer thinner immediately after use.

Lacquer Clearcoat
a.
Reduce clearcoat 125-150% with an extra-slow drying lacquer thinner to the recommended paint viscosity cup reading of the manufacturer
