I bought this set of K0 K1 black stripe decals for my Candy Gold K1. Gold paint shows through the thin and thick stripes. I can't comment on quality or ease of application and I will most likely never use them as I bought a new tank with hand painted stripes. The stripe decals will just sit in storage along with a rust treated, epoxy primered tank
Late Edit: Photo was taken in the full sun and the outer plastic film covering is reflecting the light - making the stripes appear lighter. They are very dark, inky black, and high gloss
