I recently did the whole renovo on the roof cleaner, dye and sealant (dont bother with the sealant) , its looking great now however it did not get rid of the wear marks from where the roof sits when open. After trying several products i have found this stuff to work wonders http://www.ebay.co.uk/itm/261102146889?ru=http%3A%2F%2Fwww.ebay.co.uk%2Fsch%2Fi.html%3F_from%3DR40%26_nkw%3D261102146889%26_rdc%3D1#ht_1236wt_1413 , working it into the areas on the roof when wet seems to give the best results although now I am having to trim it every few months
