After using Autoglym's convertible roof kit last year I was never happy with the results achieved. The cleaner is OK but I found the protector to be rubbish as it didn't seem to last long or even bead. Ages ago I brought some of the autoglym lifeshine range but never got round to using it and having found it in the garage I noticed I had two bottles of Fabric and Upholstery protectant. Reading what this does it is normally used for interior mats, carpets and seats and forms a barrier to protect against any spills so I thought it can't do much harm trying it on the roof. Anyway here are the results after a quick go with the pressure washer Quick video Picture not long after It was applied about 5 or 6 weeks ago now and I am pretty impressed with the results, it gives great protection when cleaning and also when it rains. It is part of the lifeshine kit, with the letter B on the bottle listed as upholstery and carpet protector or I believe a number 1 on the newer style bottle listed as interior protectant. There is some listed here at the moment on ebay, not a bad price either compared to what others cost.
