Your results are excellent! I have faced this before.
However, this is labor "intensive".
With Molotow chrome pens...in 3 sizes...you can obtain the same results, much faster. If you have a steady hand, you can outline. If not, you can quickly mask around with Tamiya tape, trim, then make a good swipe with a Molotok.
I still use BMF, for long runs of chrome...but the Molotow has made modelling easier.
