New user with a question: What cold blue works best for 'touching up' small marks on a Royal Blue finish?

Thanks.

In my experience of many years, one is about as good as another.

Brownell's sell some of the very best, and I'd recommend trying one of these.
44/40.
Dicopan T-4.
Oxpho-Blue.

Of course, the Wal-Mart and gun store Birchwood-Casey stuff works pretty good too.

One "watch-out".
Often touch-up cold blues will cause a blotch around the area where it's applied.
Try to limit the amount and the area to JUST the blemish or scratch.

Thoroughly degreasing and lightly warming the area helps.
By "warm" I MEAN warm..... NOT hot.
