Do these need to be painted before installation?

Sand and prep the surface before applying your chosen finish. Polyurethane accepts most automotive paints and can also be wrapped if you prefer. Let the finish cure fully before exposing the caps to weather.

What fasteners or adhesive do I need?

Mounting method not confirmed — dry-fit the caps first and verify alignment with your door line. Once positioned, you'll know whether bolting, riveting, or adhesive bonding works best for your setup.

Will these fit if I don't have a wide body kit installed?

These are styled to match wide body proportions. If your vehicle is stock, the caps may sit proud of the standard door line or require modification. Verify fitment against your door profile before committing to finish or fasteners.
