I have a bit of paint damage and I would like to do some touch up. A few tiny chips on my doorside (a pen would suffice) and a lot more damage on my bumper. It seems that 2015+ WR Blue models had their paint codes changed to K7X but I can't seem to find a touch up paint product with consistent results. Everything seems hit or miss... even ones with OEM tagged. Anyone have any suggestions for product? I see Dr. Colorchip often recommended but also can't find many before/after results in blue.
