we recently took our golf convertible to Padstow and the roof got attacked by seagulls who obviously decided the mohair was a better sleeping and pooing spot then the other car in the car park with steel roofs. It was a total mess when we got home. I normally use fabsil but that's just a proofer and not a cleaner. I bought the autoglym kit, cleaner and proofer, and applied it exactly as per their instructions using about half of the product.
The results are excellent - the roof looks better then ever and water beads nicely. May or may not be as long lasting as fabsil but its certainly cleaned the roof better then I anticipated
