New method development for restoration of obliterated painted registration number on vehicle registration number plate

Vehicle Registration Numbers are used as a unique identification number of any motorized vehicle, but these can be obliterated by painting during the use of vehicle in criminal activity such as murder, hit and run cases, dacoity, thefts, so that the ownership cannot be traced. Nowadays only very few methods are available for restoration of obliterated painted registration numbers on the metal plate surface. Chemical etching remains the most common and successful method for restoration of obliterated painted registration number on metal registration plate. In this study three different methods have been proposed along with 10 different etching reagents used for restoration of obliterated numbers by using a gentle and careful squeezing of the surface uniformly with a small, handy and densely rolled ball of dry cotton. Here the best results were archived with the used of method third with etching reagent R10 (composition: Carbon tetrachloride-30ml, dioxin-50ml and Ethyl acetate-20ml). The proposed third method can be best utilized along with reagent no. R10 for restoration of obliterated painted number on the vehicle registration number plate.
