I've got a felling axe to make unique marks around your cars in a way that will help you identify it after taking photos of my works of art . any good ???
Seriously ...... etched /sand blasted windows all round , front & rear both outside edges are good for visible VRN & VIN numbers , so is the DATATAG microchip security style ID chip with the VIN number for placing in discrete places that only you know of .
For £ 55 or so ... https://www.axminstertools.com/spraycraft-sandblaster-set-104153 are reasonably good . We used to have stick on masking foils that were punched out on a small portable rotary punch machine and sand blasted into it , then I vacuumed up the dust then removed the foils .
