Very nice. Please share your method. It was very clean. Also, I like the fact that you were selective in what you highlighted. Not everything is interesting enough to whiten.
The white dot came off my M&P front sight while shooting this weekend, and I thought of this thread. There's a teen aged daughter, so I tried lime green (yuck), then purple (too understated), and settled on gold.
I like it, but I doubt it will last through the next cleaning...
