Raggtopp protectant (after using their cleanser with a stiff stream of water) will darken the top a few shades. One of the British Porsche magazines had a step by step of the Renovo dye on a Boxster. Amazing result. You'll need both products. A deep cleaning is a must. And you'll have to layer the coats of the dye over several days. Many, many layers will be needed as the fabric sucks down the dye like a sponge. Apply the Raggtopp protectant to finish. And don't get regular car wash soap on it, rinse only with a super soft brush to spot clean.
