Do I need to paint each piece separately before installing?

You can paint before or after installation—either method works. Many builders spray individual pieces on sawhorses for even coverage and easier masking, while others prefer final assembly first. Both approaches are viable; choose based on your workspace and how you want to handle curing time.

What prep work do I need before painting?

Sand the surface with your chosen grit to remove any dust or sealer texture, then wipe down with a tack cloth. Apply any epoxy primer or sealer your paint system calls for, then topcoat. Follow your paint manufacturer's surface prep specs for best results.

Will I need gap filler or seam tape where the pieces meet?

Gap management depends on your fitment and how tightly the pieces sit. Have your panels test-fitted first to see if factory gaps are acceptable or if you want to close them. If you decide to seal seams, flexible seam sealers work well on FRP panels—apply before or after paint depending on your process.
