Will this cover my factory fog light holes, or do I need to cut them out?

Check your bumper's current fog light opening size and position before ordering. If your vehicle has factory fogs, you'll need to transfer or re-cut those holes to match. Reference your OEM bumper opening dimensions to mark and drill accurately on the new cover.

Can I use this with a trailer hitch, or will it hit the receiver?

Measure your hitch receiver extension and clearance from the bumper face. Because this is a GT-3 style cover with a deeper lower section, verify ground clearance and receiver distance before committing to the install. Your specific hitch type and mounting height will determine compatibility.

What prep work do I need to do before painting?

Sand the entire surface to remove the mold release agent and create texture for paint adhesion. A thorough wipe-down with a tack cloth before primer application will ensure a clean finish. Follow your paint manufacturer's guidelines for primer type and application on FRP substrates.
