Sight blackening

How are all you shooters who still use iron sights blackening your sights? Gil Hebard used to sell carbide sight blackeners years ago but I no longer see them listed.

Thanks in advance for your inputs

Look up ray vin super smoker

Burn twisted masking tape.

Bic lighter most of the time. But only if there's no breeze.

while I've still got my carbide smoker, I've used Birchwood Casey sight black, burned target pasters, masking tape, and bic lighters.

For simplicity sake I just use the bic lighter now, I just leave a small one in my gun box all the time.

Ray Vin super smoker for my guns...

Flat black spray paint.

+1 on the Ray Vin.
I have one in my pistol gear and one in the rifle gear

There is the convenience factor of the sprays but nothing is blacker than carbide..  Champion's Choice has the Ray Vin tool..

Never a reflection off carbide..

Thanks to everyone for their suggestions. They are greatly appreciated.
