Yea my intention for passing this info was for those who would like to DIY and for those who do not have a lot of experience in modding or painting parts etc.. so I've been testing different things.
I'm trying to find the best and closest to the gen color without getting complicated and here's how I did that 116610LN insert ... with a silver metallic sharpie marker, a 2 pack for $6.99 at staples ? Lol it works and it's damn close to the gen color. Just filled the indices and rubbed over with fine micro fiber cloth to take away the access on the polished part of the ceramic.
This is still preliminary and im still testing other things and have a few pretty cool markers ordered that actually have metal in them like the silver sharpie. So once I get them and try I'll post photos and what I have tried, I'm also going to see how durable the sharpie that I used is, but I'm guessing it's quite good because I use the black and other colors for marking steel through hyd fluid and grease etc.. at work.
Cheers !
