Had a spare couple of hours at work yesterday so masked the roof of the car off and applied 3 coats of a product called Ragg-topp to the soft top. first impressions the hood looks much darker than the G techniq roof protection (which is still a good product,but started to wear off after a couple of weeks)and also the water repellancy seems to be much stronger, its a genuine oem porsche part (apparently!)that their hood manufacturer uses on the fabric.I threw a cup of cold water on it today and the results were impressive!!! Time will tell how long it lasts tho!!!
