Looking forward to learning how to fix my roof and spoiler problems. Have read lots of threads in this so trying a few of them. New battery was first. Car (2007 Roadster) is usually garaged in winter but this year decided to keep it on the road. Roof had lost its waterproofing so think there might have been water ingress or damp. Roof now had its waterproofing on and car now in my garage. Will try out some of the suggestions on the posts and let you all know what happens. Any further suggestions will be most welcome.
