Re: Plastic snap Caps?
Something else you may like to try, depending on what type of plastic they're made from you may be able to dye them. The hot dyes used for dyeing nylon and other man-made fabrics work on many "solid" plastics too, and once dyed the colour is permanent, it can't chip or flake off as paint does.<br />Start with white ones and use a black dye, experiment with individual caps to see how long they need to soak to achieve the shade of grey, then dye a whole batch at the same time.
