Ive seen an increasing number of install projects online on MRAPs and MaxxPro vehicles, so I wanted to put a comprehensive post together for installers. This is a cautionary post for anyone working on these vehicles, and to share with anyone who plans to repaint these.
First, the topcoat on the exterior and interior of these vehicles is Sherwin-Williams CARC, and may vary depending on what BAE or Oshkosh used that day. Most common components of the coating will be:
Methyl n-Propyl Ketone
Methyl n-Amyl Ketone
Titanium Dioxide
Methyl Isoamyl Ketone
n-Butyl Acetate
Isophorone Dilisocyanate
Hexamethylene Dilisocyanate Polymer
Chromium Oxide
Napthalene
Xylene
Toluene
Ethylbenzene
Cobalt Chromite
Basically, for anyone who's ever taken a HAZMAT/HAZWOPPER class, all that methyl-ethyl-bad shit we were taught to fear. Now, most of this the biggest danger is dealing with these coatings while in wet form during application. However, extreme caution is needed when drilling or sanding down for any work or equipment installation.
ROUTES OF EXPOSURE
INHALATION of vapor or spray mist.
EYE or SKIN contact with the product, vapor or spray mist.
EFFECTS OF OVEREXPOSURE
EYES: Irritation.
SKIN: Prolonged or repeated exposure may cause irritation.
INHALATION: Irritation of the upper respiratory system.
May cause nervous system depression. Extreme overexposure may result in unconsciousness and possibly death.
Prolonged overexposure to hazardous ingredients in Section 2 may cause adverse chronic effects to the following organs or systems:
the liver
the urinary system
the hematopoietic (blood-forming) system
the cardiovascular system
the reproductive system
SIGNS AND SYMPTOMS OF OVEREXPOSURE
Headache, dizziness, nausea, and loss of coordination are indications of excessive exposure to vapors or spray mists.
Redness and itching or burning sensation may indicate eye or excessive skin exposure.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
May cause allergic respiratory and/or skin reaction in susceptible persons or sensitization. This effect may be delayed several hours after
exposure.
Persons sensitive to isocyanates will experience increased allergic reaction on repeated exposure.
CANCER INFORMATION
For complete discussion of toxicology data refer to Section 11.
SECTION 4 — FIRST AID MEASURES
EYES: Flush eyes with large amounts of water for 15 minutes. Get medical attention.
SKIN: Wash affected area thoroughly with soap and water.
If irritation persists or occurs later, get medical attention.
Remove contaminated clothing and launder before re-use.
INHALATION: If any breathing problems occur during use, LEAVE THE AREA and get fresh air. If problems remain or occur later,
IMMEDIATELY get medical attention.
INGESTION: Do not induce vomiting. Get medical attention immediately.
PRECAUTIONS TO BE TAKEN IN USE
Use only with adequate ventilation.
Avoid contact with skin and eyes. Avoid breathing vapor and spray mist.
Wash hands after using.
This coating may contain materials classified as nuisance particulates (listed "as Dust" in Section 2) which may be present at hazardous
levels only during sanding or abrading of the dried film. If no specific dusts are listed in Section 2, the applicable limits for nuisance dusts
are ACGIH TLV 10 mg/m3 (total dust), 3 mg/m3 (respirable fraction), OSHA PEL 15 mg/m3 (total dust), 5 mg/m3 (respirable fraction).
VENTILATION
Local exhaust preferable. General exhaust acceptable if the exposure to materials in Section 2 is maintained below applicable exposure
limits. Refer to OSHA Standards 1910.94, 1910.107, 1910.108.
RESPIRATORY PROTECTION
If personal exposure cannot be controlled below applicable limits by ventilation, wear a properly fitted organic vapor/particulate respirator
approved by NIOSH/MSHA for protection against materials in Section 2.
When sanding or abrading the dried film, wear a dust/mist respirator approved by NIOSH/MSHA for dust which may be generated from this
product, underlying paint, or the abrasive.
PROTECTIVE GLOVES
Wear gloves which are recommended by glove supplier for protection against materials in Section 2.
EYE PROTECTION
Wear safety spectacles with unperforated sideshields.
OTHER PRECAUTIONS
Intentional misuse by deliberately concentrating and inhaling the contents can be harmful or fatal.
CHRONIC HEALTH HAZARDS
Reports have associated repeated and prolonged overexposure to solvents with permanent brain and nervous system damage.
Crystalline Silica (Quartz, Cristobalite) is listed by IARC and NTP. Long term exposure to high levels of silica dust, which can occur only when
sanding or abrading the dry film, may cause lung damage (silicosis) and possibly cancer.
IARC's Monograph No. 93 reports there is sufficient evidence of carcinogenicity in experimental rats exposed to titanium dioxide but
inadequate evidence for carcinogenicity in humans and has assigned a Group 2B rating. In addition, the IARC summary concludes, "No
significant exposure to titanium dioxide is thought to occur during the use of products in which titanium is bound to other materials, such
as paint."
Reports have associated repeated and prolonged overexposure to solvents with permanent brain and nervous system damage.
Naphthalene is classified by IARC as possibly carcinogenic to humans (2B) based on inadequate evidence in humans and sufficient evidence
in laboratory animals.
Ethylbenzene is classified by IARC as possibly carcinogenic to humans (2B) based on inadequate evidence in humans and sufficient
evidence in laboratory animals. Lifetime inhalation exposure of rats and mice to high ethylbenzene concentrations resulted in increases in
certain types of cancer, including kidney tumors in rats and lung and liver tumors in mice. These effects were not observed in animals
exposed to lower concentrations. There is no evidence that ethylbenzene causes cancer in humans.
Cobalt and cobalt compounds are classified by IARC as possibly carcinogenic to humans (group 2B) based on experimental animal data,
however, there is inadequate evidence in humans for its carcinogenicity.
Crystalline Silica (Quartz, Cristobalite) is listed by IARC and NTP. Long term exposure to high levels of silica dust, which can occur only when

Lot of MSDS info here, but wanted to put it all in one post for those who work on these trucks. These are fun to work on, but make sure appropriate measures are taken when dealing with this stuff.
Instead of sanding down these trucks, use a paint stripper and scrapper to remove large areas of paint. One of the coolest things too about CARC paint is that its already a damn good primer/base coat. Just paint over the stuff unless a gloss finish is desired, then use your head while prepping.
