thanks guys,
gonna scout off to tescos and get a spray bottle, vingar and some kitchen roll!!
didnt think it was limescale, just thought it was water marks but looking at some of those pics, it could be early days lime, and ... well i think i got off pretty light!!
thanks guys!
... oh and on a side note, was AMAZED no water got in during the first burst! I know its a coupe, but all the seals were perfect! not a drop inside! My old megane coupe used to let water in like the titanic through the sun roof even in a drizzle!
