Fix a roof gutter

I repaired a roof rail with Sugru at 20.08.2013. It was the "last hope" to fix the untight roof rail after trying this and that. Meanwhile the Sugru fix has "experienced" some very cold winter (more than -5° Celsius) and very hot summer (more than +35° Celsius). It is still fixing the untight roof rail, not 100% as in the first year, but since then about 95 percent tight (excuse my English, please).
