if you are a long way from the source you could find black spray on rubber useful. have just been recomissioning my spots and found this great on the spot bases and cracked rubber washers that go under them , have also used it on a 3d remake of my broken switch cowl round the steering column , my son has the design of mine and can make one if anyone requires one though at this stage i think colours may be limited , the product is called plastidip and is made by performix , ihave just discovered that it is available in assorted colours, to clarify the cowl was printed in black abs and the it needed a few coats of plastidip to improve the finish
