4Bush WRS

4Bush WRS handles professional firearm finishing and customization at their Arnold, Missouri location inside Top Gun Range. Their specialty is Cerakote—a ceramic-polymer coating that's been independently tested against traditional firearm finishes and wins across every metric.

Cerakote's ceramic backbone delivers measurable advantages:

• •Abrasion Durability - Testing shows 7.5x more wear resistance than competitors. Standard finishes fail around 500-600 cycles; Cerakote doesn't fail until 8,000+ cycles.

• •Corrosion Protection - Salt spray testing (ASTM B117) proves Cerakote protects 50 times better than other finishes. After 385 hours of salt spray, Cerakote-coated steel showed zero corrosion.

• •Impact Resistance - Flexibility testing shows 32% elongation with no coating loss under 160 lbs/sq in impact.

• •Hardness - ASTM D3363 rates it at 9H pencil hardness and 6H scratch resistance—among the best results on any coating.
