The seals running along the length of the roof on our 2014 Sterling Elite have developed black spots. This happened very soon after we took delivery and has got steadily worse. I have tried scrubbing them with a range of cleaning compounds, but the black stain appears permanent. I've sent details to Swift, asking for advice - who have yet to respond - but while I'm waiting, I'm curious if anyone else has a similar problem. The roof seals between the roof and the front and back fairings are taped, which isn't affected - and I've asked Swift if applying this tape over the existing sealant is acceptable and effective.
