This spoiler set is for replacement if the original one is damaged or broken beyond repair. Specifically meant for our new Topline roof produced out of white ABS. For our older Scania Topline roof, produced out of Raisin, you should choose the TA05 Spoilerset, ( a yellow, crème coloured item.) Before painting, please make sure the surface is decreased firmly Also we do advise a first layer of plastic primer, to assure good fixation. This set contains all standard mount materials.
