Component Description:

Frame Rail

Subject:
Proper Repair of Frame Rail Corrosion
Purpose/Background:
To consolidate the ASY Galvanized and E-Coat Frame Rail Repair Procedures into a combined communication to
provide proper instructions for repairing frame rails that have corroded due to wear/chipping over time, road
salt/brine, humidity, and improper cleaning after use.
Description/Procedure:
Galvanized Repair Procedure (PSD-0259)
Paints containing zinc dust with a concentration of 92% or above dried film (ZRC Galvilite recommended and
used in procedure).
Materials
•
•

ZRC Galvilite
Sikkens M600 Solvent Degreaser

ZRC Galvilite Benefits
•
•
•
•
•
•
•

95% zinc in the dry film using only Type III “ultra-pure” ASTM-D-520 zinc (lead & cadmium free)
Recognized under the Component Program of UL as equivalent to hot dip galvanizing
Meets and exceeds Fed. Spec. DOD-P-21035A, MIL-P-26915A and ASTM Des. A-780
Passes 3,000 hours salt spray testing without failure (ASTM Des. B117)
Passes 9-year subtropical testing
Low VOC approved in all 50 states
ISO 9001 registration assures the highest quality consistently

Mixing
ZRC Galvilite must be thoroughly stirred until pure zinc content is completely dispersed. Initial mixing can be
done with a paint shaker.
Procedure
1. Remove loose galvanized coating.
a. If there is any pitting involved, needle scaling may be required.
b. Sand repair areas to a featheredge finish.
2. Remove grease, oil, and/or light oxides with Sikkens M600 solvent degreaser.
3. Apply ZRC Galvilite with a brush without thinning, to achieve a thickness of 2.0 mils. (One medium to
heavy coat will achieve the proper film build).
4. Replace the cover on the can to avoid the product from hardening.

5. Allow coating to dry until dry to touch, in 20-30 minutes. Times may vary depending on thickness applied,
substrate temperature, and ambient temperature.

Wax and grease removing solvent
Bonderite Auto Prep Wipe
Sikkens LV260 Primer Epoxy
Sikkens LV260 Hardener
Sikkens LV262 Multi-Substrate Primer Epoxy
Sikkens LV262 Epoxy Hardener G2
Sikkens LV650 Topcoat Low Gloss Black (Pierce #99)

Procedure
1. If there is any pitting involved, needle scaling may be required.
2. Solvent wipe surface to be coated with a wax and degreasing solvent. Reference PSD-0084 (See
Appendix A).
3. Wipe bare metal areas to be coated with a Bonderite Auto Prep Wipe.
4. Sikkens LV260 Primer Epoxy or LV262 Multi-Substrate Primer Epoxy must be used to coat the bare metal
areas.
a. Sikkens LV260 Primer Epoxy uses 3 parts to 1-part LV262 Epoxy Hardener
b. Sikkens LV262 Multi-Substrate Primer Epoxy uses 3 parts LV262 Multi-Substrate Primer Epoxy
to 1-part LV262 Epoxy Hardener G2
5. Mix appropriate amount of epoxy primer for the size of the repair.
6. For all non-critical aesthetic areas, the epoxy primer may be applied with a paint brush.
7. To apply the epoxy primers with spray application equipment, reference PSD-0205 (See Appendix B) for
LV260 Primer Epoxy or PSD-0286 (See Appendix C) for LV262 Multi-Substrate Primer Epoxy.
8. Apply 1-2 coats of epoxy primer to achieve full coverage.
9. Allow epoxy primer to flash off until it is dry to the touch.
10. The area that the epoxy primer was applied to, will need to be coated with Sikkens LV650 Topcoat Low
Gloss Black (Pierce #99).
11. Mix appropriate amount of LV650 Topcoat Low Gloss Black for the size of the repair.
a. Sikkens LV650 Topcoat Low Gloss Black uses 6.5 parts LV650 Topcoat Low Gloss Black to 1part LV650 Hardener
12. To apply the LV650 Topcoat Low Gloss Black with spray application equipment, reference PSD-0217
(See Appendix D).
13. Allow LV650 Low Gloss Black to dry for 3 hours if ambient temperature is 70°F if assembly of the part is
required. Adding heat to the area will decrease the cure time.
