I’ve owned my Spider for nearly 3 years now. My routine has been to clean the hood and re-waterproof it a couple of times a year using Autoglym products. Usually the same time as it gets its big clean and I change from summer wax to winter wax and vice versa. When I first got the car, I also treated the hood with Renovo colour restorer. Fast forward three years and it needs another go with the Renovo to get it looking it’s best. Despite a very thorough clean, the waterproofing is still very much doing its thing so the Renovo isn’t soaking in very easily and has dried looking almost shiny and well, a bit crap really. Certainly not as good as the first time. Anybody else had this problem or got any suggestions? With thanks in advance.
