3.0 EXECUTION

3.1 Workmanship: The performance of all work will be in accordance with industry standards, best practices and applicable state local and federal safety and environmental rules and regulations. Public image is very important to ARRC and the major purpose in undertaking this work is to promote that image including appearance and stewardship.

3.2 Surface Preparation

NOTE: The contractor is hereby advised that many passenger cars still in service were built long before lead-based paints went out of favor and it is most likely that such paint will be found on them.

3.2.1 Surfaces shall be prepared in accordance with paint manufacturer’s requirements and recommendations to the extent that they exceed this specification. The contractor shall bring to the attention of ARRC’s project manager for resolution any conflict between these specifications and the manufacturer’s published data. Tables 3 and 4 provides summary directions for surface preparation based on the substrate and maintenance painting requirements. Do not conduct final surface preparation unless the substrate temperature is a minimum of 5oF above the dew point. Provide clean dry compressed air for all operations where air may be used for surface preparation, surface blow-down, and coating application.

3.2.2 Cleaning- Prior to beginning surface preparation power wash and solvent clean (SSPC-SP 1) all surfaces to be prepared and coated. Use cleaning aids acceptable to the Engineer as necessary to remove soot, soils, sap, and surface dirt. Do not conduct surface preparation unless the substrate temperature is a minimum of 5oF above the dew point.

3.2.3 Spot Repairs- All areas of rust, corrosion, defective paint, cracked, lifting, deformed or otherwise defective caulks, sealers and fillers and oxidation shall be removed Exposed bare metal shall be solvent cleaned and prepared by abrasive blast cleaning (SSPC-SP 6) or may be prepared using power tool cleaning (SSPC-SP 11 or SSPC-SP 15). Produce an anchor profile of 1.5 to 2.0 mils as measured in accordance with ASTM D4417 Method C. Any defects on passenger cars requiring more than 1/8" of filler shall be brought to the attention of ARRC and work held pending a decision as to best method for repair.

Prepare existing adherent existing coating that will remain around the spot repair by sanding using hand or power tools (SSPC-SP 2 or SSPC-SP 3).

Feather the edges of the coating around all spot repairs a minimum of 2 inches onto the existing coating and provide a smooth transition for the coating to be applied. Note that removed caulks, sealants and fillers will be replaced in kind. 3.2.3.

3.2.4 Spot Repairs and Overcoating- Perform spot repairs as required in Section

3.2.2. Adherent paint that will remain and be overcoated shall be etched or sanded in accordance with SSPC-SP 3 or SSPC-SP 7 for Steel and SSPC- SP 3 or SSPC-SP 16 for Aluminum and/or Stainless Steel.

3.2.5 Removal and Replacement- Complete or zone removal6 of the existing coatings shall be performed by abrasive blast cleaning in accordance with SSPC-SP 6. Provide an anchor profile of 1.5 to 2.0 mils as measured in accordance with ASTM D4417 Method C. Conduct the cleaning with care when moving from steel to aluminum or stainless steel surfaces to avoid excess damage and unacceptable anchor profiles.

3.2.6 Use of Abrasives- Whenever abrasive blasting is performed; protect all surfaces not to be painted from damage and contamination by abrasives.

This shall include air intakes, vents, bright metal, glass, gaskets, machined surfaces and mechanical and electrical equipment. All dust, abrasives and other interference materials shall be removed before priming.

3.2.7 Cleanliness-Verify the degree of cleanliness meets the applicable surface preparation criteria. Use SSPC-Vis 1 as an aid in evaluating surfaces prepared by abrasive blast cleaning. Use SSPC-Vis 3 as an aid in evaluating surfaces prepared by hand and power tool cleaning.

3.3 Seams and Uneven Surfaces

All seams and uneven surfaces, dents (depressions) in surface shall be roughened, feathered out primed and filled with compatible body filler suitable for temperature extremes of -60 to +100 F. Some patch work may need to be continuous from seam to seam, to prevent an undesirable finish variation. Old lettering (unless it is to be reapplied) shall be sanded out or filled so as to be illegible after application of the primer coat.

3.3.1 In preparation for painting, girder sheets shall be repaired and any loose side sheeting re-secured using fastening techniques standard to the car’s original construction.

3.3.2 Holes, large dents, tears and corroded areas shall be patched (by welding with applicable type of stainless steel, aluminum or steel rod). Small dents (up to 1/8" deep) shall be filled using an epoxy or polyurethane body filler.

Patch all damaged areas. Priming of mild carbon steel and non-ferrous metals shall be done before occurrence of any corrosion (detectable by eye or touch). Total film thickness of primer shall be 5 to 6 mils (wet) applied in one coat.

6 Zone removal refers to large surface areas that require removal and replacement but not to the extent that the entire car requires maintenance painting. For example, the work may be limited to trucks or roofs.

3.4 Application

3.4.1 All materials shall be applied and allowed to cure in strict accordance with manufacturer’s requirements and recommendations. All applications and curing shall be done in a warm, dry and dust free atmosphere.

Ambient Conditions - Apply coatings under the following conditions unless the requirements of the coating manufacturer are more restrictive. .

Surface and Air Temperatures - Between 50ºF and 110ºF.

Relative Humidity - Less than 85%.

Dew Point - Surface temperature at least 5ºF above the dew point temperature of the surrounding air.

Frost/Rain - Do not apply coatings to surfaces containing frost or during rain, fog, or similar conditions.

Remove and replace any paint that is exposed to unacceptable conditions (e.g. rain or dew) prior to adequate curing.

It is the responsibility of the contractor to assure that the old finish is compatible with the new materials for spot repairs and overcoating. Any rework necessary due to reaction between the two materials shall be performed at no charge to ARRC.

3.4.2 Pre-treat prepared bare aluminum surfaces with Dupont WP™ Chrome-

Free Wash/Etching Pre-Treatment Primer Primer Urethane DFT 3-5 Primer Epoxy Mastic DFT 5-8

3.4.3 Primer shall be applied immediately after completion of surface preparation. In the case of bare metal, it shall be completed before the formation of any oxides.

3.4.4 Total film thickness of primer shall be 5 to 6 mils.

3.4.5 Finish coat and lettering

3.4.6 Finish coats shall be applied well within the time limits after immediately prior coat as specified by the paint manufacturer.

3.4.7 Application shall consist of two coats totaling 1.5 to 2 mils DFT.

3.4.8 Lettering shall be applied as shown on the detailed diagram.

3.4.9 Required lettering and logos will be painted on and cleared over.

3.4.10 Edges of all logos and any other decals or Scotch-Lite shall be sealed with a coat of clear lacquer prior to final (clear) coat.

3.4.11 Final Coat: After all painting and lettering is complete the entire car body shall be given one coat of Dupont Imron 3.5 HG-C™ clear-coat within the recoat window of the pigmented finish coats. The finished product shall present a high gloss “wet” appearance.
