The 2007–2013 GMT900 Silverado/Sierra paint is decent but not bulletproof. The hood front edge is especially vulnerable to rock chips, and the rockers take a constant beating from road debris. Here’s the best way to protect your truck’s paint long-term.
Why Protect the Paint on a GMT900?
Many GMT900 trucks still have original paint in good shape, and preserving it is far cheaper than repainting. The most vulnerable areas are:
- Hood leading edge (rock chips from highway driving)
- Rocker panels (debris, ice, salt spray)
- Front bumper lower
- Door lower edges
Option 1: Ceramic Coating (Best Long-Term Protection)
Ceramic coatings create a hardened SiO2 layer over the paint that repels water, dirt, and minor scratches. A consumer-grade ceramic coating applied at home can last 1–2 years.
Chemical Guys HydroSlick SiO2 Ceramic Coating Wax – Easy to apply, excellent hydrophobic properties, and adds deep gloss.
How to Apply:
- Wash and decontaminate paint (clay bar)
- Correct any scratches/swirls (optional)
- Apply product panel by panel
- Buff off residue
Option 2: Paint Protection Film (Best Rock Chip Resistance)
Clear PPF on the hood leading edge and rockers is the best protection against rock chips. Self-healing PPF heals light scratches with heat.
Option 3: Spray Wax / Quick Detailer (Maintenance)
Regular use of a spray detailer or spray wax extends the life of any coating underneath. Apply after every wash.
Rocker Panel-Specific Protection:
Consider 3M VHB tape or rock guard paint/film on the lower rockers if you do off-road driving or drive on gravel roads. The factory paint on the rockers chips easily.
Maintenance Schedule:
- Wash every 1–2 weeks
- Apply ceramic spray or spray wax every 2–3 months
- Full decontamination (iron remover + clay bar) 1–2x per year
