I used PPG when my 7 was repainted in 2015 and I had the film added to the nosecone, rear wings, scuttle, cockpit bows (?) and the area behind the bonnet springs. Yes, there are a few scuffs from flying stones on the rear wings but more importantly the film hasn't 'yellowed' over the white strip on the nosecone. Not cheap but well worth it in my opinion.
