Always ensure the vehicle is clean of contaminants prior to application. 

We would not recommend applying any vehicle graphics/wrap to paintwork that is damaged or substandard 

About us: By trade we are a vinyl wrappers but are occasionally asked to supply and fit vehicle graphics, once we have the artwork for the graphics we will list spare sets of graphics on ebay. So we only sell graphics that we know are correct for that vehicle, because we have fitted them to that make and model ourselves, hence we do not list a wide range of graphics! We are trained by 3M and only stock 3M 2080 wrap films for sale, all vinyl sold is excess vinyl that has been over ordered from a job and remains in date (this is key, all vinyls have a shelf life prior to application before the adhesive begins to break down)
