We have specific instructions for type III anodizing. (Our new system is type II.)
Type III is a difficult process, even for the professional shops.
What is worse is that most people wouldn't be able to tell type II from type III, and so, when type II is produced and sold as type III, no one is any the wiser.
The difference in hardness between the two is minute.
Most people asking for type III are thinking it is HARD anodizing, as if type II were SOFT. This simply isn't the case.
Another common mistake is that they ask for HARD anodizing, yet want it dyed. That's a dead giveaway. Type III is never dyed.
Don't be fooled by HARD anodizing - ALL TYPES OF ANODIZE ARE HARD
