Will I need new fasteners to bolt this on?

Factory mounting holes align with existing attachment points on the frame. Check that your truck's fastener hardware is in good condition before install; replace any rusted or stripped bolts with new hardware rated for exterior trim mounting.

What do I need to do to prepare this for paint?

Light sand the primed surface with 180–220 grit to scuff the finish, then clean with a tack cloth before priming or painting. Follow your paint supplier's prep and application instructions for best adhesion and color match.

Can I return this if it doesn't fit right?

Inspect the panel and test-fit it to your truck before finishing work. Contact ModSupply customer service if you encounter fitment issues—they'll walk you through troubleshooting or process a return.
