Non-Reflective, NiAc Seal

[prepare]

Is the Non-Reflective, NiAc Seal just a seal?

Wondering if it has any hardening properties?

Its definitely a nice finish on uppers/lowers and rails.

Aluminum is precipitation hardened before machining.

I don’t see any reason plugging the holes in anodizing would increase hardness. It is low temperature and isn’t a coating or surface conversion.

SOLGW/ ZEV/MEGA use it.

It seems to resist scuffing pretty good. Beyond that it looks good.
