ALUMINUM BODY PAINT SPECIFICATIONS

BODY PAINT PREPARATION

After the body and components have been fabricated they shall be disassembled prior to painting so when the vehicle is

complete there shall be finish paint beneath the removable components. The body shall be totally removed from chassis

during the pain process to insure the entire unit is covered. The body and components shall be metal finished as follows

to provide a superior substrate for painting.

The exterior body shall undergo a thorough cleaning process starting with a biodegradable phosphoric acid solution to

begin the etching process followed by a complete clear water rinse. The next step shall consist of a chemical conversion

coating applied to seal the metal substrate and become part of the metal surface for greater film adhesion. If the

compartment interior is to be painted the interior shall be acid etched as described above then primed with an epoxy

primer and all seams caulked.

All bright metal fittings, if unavailable in stainless steel or polished aluminum, shall be chrome plated. Iron fittings shall be

copper under plated prior to chrome plating.

PAINT PROCESS

The paint process shall follow the strict standards set forth by PPG Industries guidelines. Painters applying PPG products

will be PPG Certified Commercial Technicians, and re-certified every two (2) years.

The body shall go through an eight-stage paint process;

1. Clean bare metal using a solvent base wax & grease remover.

2. Finish all exterior body seams as necessary, followed by a thorough sanding of all bare metal to be painted.

3. Re-clean bare metal using a solvent base wax & grease remover.

4. Bare Metal Epoxy Primer Coat - PPG Delfleet® Evolution corrosion resistance epoxy primer to be applied at 1.0-

2.0 mills DFT over clean abraded bare metal.

5. Primer Filler Coat - PPG Delfleet® Evolution urethane build primer to achieve total thickness of 3.0-6.0 mils DFT

after sanding.

6. Base coat (Color) - PPG Delfleet® Evolution High Solids Polyurethane Base coat. Apply 1.0-3.0 mils DFT of base

coat color to achieve full hiding.

7. Clear coat PPG Delfleet® Evolution polyurethane premium quality clear coat with improved mar resistant finish.

The clear coat shall be applied to achieve a total dry film thickness of 2.0-3.0 mils.

8. Curing process of the painted body shall go through a force dry/bake cycle process. The painted components

shall be baked 180 degrees for 2 hours to achieve a complete coating cure on the finished product.

MACHINE POLISHED

After the force dry/bake cycle and ample cool down time, the coated surface shall be sanded using 1,000, 1,500, and or

3,000 grit sandpaper to remove surface defects. In the final step, the surface shall be buffed then polished to an extra high

gloss smooth finish. Total dry film thickness of paint will average between 8.0-12.0 mils.

PAINT - ENVIRONMENTAL IMPACT

The contractor shall meet or exceed all current State (his) regulations concerning paint operations. Pollution control shall

include measures to protect the atmosphere, water and soil. PPG Delfleet® Evolution paint shall be free of all heavy metal

(lead & chromate) components. Paint emissions from sanding and painting shall be filtered and collected. All paint wastes

shall be disposed of in an environmentally safe manner. Solvents used in cleanup operations shall be collected, sent off-

site for distillation and returned for reuse.
