^^ I'm not quite sure what you mean.
I'm guessing you're saying that they won't be flush with the rest of the paintwork(?). If that's it, then yes. The decal's would be raised. But that is kina the point.
They wouldn't look as cheap as vinal decals, they would be hard wearing, and it would suit the custom-look of the frame and brand.
(all imo obvs)
Another option is 2PAC paint. Limited colour options, but apparently somewhere in-between.
^ and Langsters clearly do not belong here. They are a well priced, sensible all-rounder, that comes with some decent parts as standard. There is nothing slave about them.
where powder is quite thick it will probably leave the alloy decal's recessed with a colour edge around it!
2k colours will be limitless as its car colours
