Thanks a lot for the compliments. You all have been very encouraging and I appreciate it.
As for the method... I have found that by using a silver leaf paint pen, I could draw on the chips. Then to make the repair look "more real" from my point of view, I painted white with a Testor's Gloss White paint pen around the edge to reduce or cover where paint would have chipped off.
Here is my reasoning...
If you were wearing something like this, you would make attempts to keep it in a condition, or color, as it was issued to you. So, some light damage occurs from combat, the elements, whatever. You would try to recondition the suit, and helmet, in the field (using your trusty Mandalorian-Issued Armor Paint Chip Repair Kit.), but that would wear off easier, therefore any new damage or exposure would cause your re-paint to chip away... easier. Does that make sense?
Plus, it was a bit easier than masking, and gives a similar result since the white repaint hides the level of the silver being a top coat versus a demasked base-coat. Does that make sense too?
Later Friends,
