I just picked some up to touch up a few scratches.  It seemed to work well and quickly. How important is the cold water rinse off and in the end will this stuff stay on and keep its color?

I took the cold water rinse thing and mine turned out great.  Make sure your wearing gloves.

It has a lot of chemicals in it and has been known to cause cancer.  Not to mention you could be allergic to them.

Perma-blue is a touch-up blue and is suitable only for small areas on steel parts.

It has the advantage of being easy and quick to apply; the downside is that it’s not especially durable.  It’s great for covering up a scratch or such, but will wear off pretty quickly in a high friction area such as the muzzle of a handgun where it rubs against a holster.

In my case at least, it tends to burn my skin.  I take great pains to avoid contact with it and usually apply it with a Q-tip.

I’ve never found the rinse to be necessary.  However, I always polish the touched up area with a clean patch or such and then oil things well.

I made my stock Sig trigger into a short trigger and used perma-blue to refinish it.  The perma-blue didn't wear off, and thats pretty good considerering the refinish part was the trigger face.  

I followed the instructions and used about 5 or 6 coats.

The rinse off is important because the blue is a type of acid, and it will continue to react with the metal until rinsed off.

If it is a type of acid would it be good to swab the surface with ammonia afterwards to neutralize it? Or would that damage the blue?

I'd just use water per the instructions.  The residue washes off with no problem.

DO NOT LICK THE PIN! It will mess you up. It works ok but I like dicropan better.
