When installing W-Braces at Tarmac Sportz, we regularly find that the original kidney braces the W-Brace mounts to are heavily corroded due to age and exposure to the elements. It's also common for the original mounting bolts to seize and snap during removal.
These are powder coated to provide improved corrosion resistance over the original factory finish. In our experience, the OEM coating offers limited long-term protection, so powder coating helps extend the life of the braces and keeps them looking their best.
