please can anyone advise. I have a new ace award firestar that we have used very little since we took delivery in feb this year.we have noticed that an odd mark within the window is becoming more vivid,dead centre, of the main front window.it looks a bit like a kid would draw a seagull in flight.a bit like a V.it is on the inside area of both the inner and outer panels,about 10 inches across, and its identical...just as if you`ve held a transfer between your palms. i do intend to show the supplying dealer, but its a bit of a trip from our storage.so any info beforehand would be helpfull...many thanks..nigel.
