Hi Alan, I bought mine at a model engineering show, a pinstriping set by 'BEUGLER' a USA company. My kit has three sizes of pinstrip,1/16,1/8 and 3/32, they have a wide selection of sizes, try them on the website, not cheap but good quality. Peter
Hello! In my case, I use vinyl car decorative stripes. Ebay offers them very cheap, less than US$4.00 with shipping and everything. Once I apply them, I use a hairdryer to melt the vinyl a little bit. With this method they stick very well.
