Do I need to sand and prime this before painting?

The cap Requires Surface Prep, so the surface is already prepped to accept paint. A light scuff with fine-grit sandpaper and a dust wipe is all that's needed before applying your chosen primer and top coat.

Can I use this cap on a partial wide body setup, or does it require the full kit?

This cap is engineered to work as part of a complete wide body conversion. The styling and proportions are designed to align with full kit geometry, so verify all matching body components are in place for proper fitment and visual balance.

How do I secure the cap once installed?

Reference your vehicle's original fuel door latch and mounting point to determine fastener requirements and installation method. Ensure the cap aligns with the factory opening before final securing.
