Ive got a set of mike buffs no chance of getting stencils tried everywhere even tried having them laser etched but they melted luckily tried on inside of rim first
You could bleach them with hair products and UV from the sun.
I did a set off M Buffs and they came up super white and then got standard decals from Del.
You could go down that route mate..
I did try Del at First for Graphite stencils but he didn't do them .
When they arrived I sent off a few scans and pics of the original decals and the stencils too Del for any future inquires in Feb .
I just emailed him today and is looking into doing a set as we speak..
So fingers crossed these will be ready for my next build..
