Do I need to sand and prime before painting?

Yes. Sand the FRP surface with appropriate grit and apply a primer coat suited to your topcoat system. This ensures proper paint adhesion and finish durability. Consult your paint supplier for primer and grit recommendations based on your chosen finish type.

What hardware do I need to install these?

The scoops ship as bare components. You'll need standard metric bolts, washers, and lock nuts to secure them to the factory mounting points on your rear quarters. Check your vehicle's service manual or a forum-specific install guide for the correct fastener size and torque specifications.

Will these scoops fit if I've modified my rear quarters?

These scoops are designed for factory rear quarter panel geometry. If your quarters have been heavily modified, reshaped, or reinforced, test-fit before final fastening. Verify alignment with your existing mounting holes and panel contours to ensure a flush fit.
