Man... I look back at my posts from nearly a year ago saying, "I'm gonna do it soon!" HAH! What a schmuck I was...

But such is life.

In this post by Mssr. Shaffer, he used a glyoxal pre-hardener and his results suggest that it was necessary.

I've got chrome alum, so I'm thinking to try a 3% solution for 4 min. Then proceed to develop with a 2-part GP-2 developer, followed by a wash. I've also got some sorbitol incase it needs to be post-swelled.

Anyways, first time using a hardener so just want to make sure that sounds like a good % and time.

Cheers y'all

edit: Oh, and is a wash after the hardener necessary or would it be detrimental?
