Do I need to sand or prep the primer before painting?

Light scuffing with fine-grit sandpaper improves paint adhesion. Clean with soap and water, let dry completely, then apply your color coat per the paint manufacturer's instructions.

What fasteners do I need to install this?

Mounting method and hardware specs are not detailed in the product data — test-fit the cover first, then source fasteners or adhesive based on your specific attachment point and vehicle condition.

Can I return this if the fit doesn't work?

Contact ModSupply's customer service with photos of your fitment concern — they'll walk you through returns and exchanges based on the condition of the item received.
