I've used two Specialised covers on my (red) Golf over nine years. The first one got badly burned when the neighbour did something with his woodburner which burned over 60 holes in it.
The second one has survived, but certain weather conditions cause serous condensation under the cover. I no longer use it because after nine years abrasion has revealed a thin strip of primer on a crease line, and sundry other wear patches in the lacquer.
I always cleaned the Golf before putting it on.
