What's the best way to prep FRP before painting?

Sand the entire surface with medium-grit paper to open the gelcoat, then wipe clean of dust. Apply your choice of primer and topcoat per the paint manufacturer's instructions. FRP accepts most automotive finishes when properly prepped.

Does this require drilling new holes in the bumper?

The diffuser is engineered to use existing factory mounting points. Before installation, verify that your bumper's attachment holes align with the diffuser tabs—minor fitment adjustment may be needed depending on bumper condition or prior modifications.
