I don't understand, why would this be bubba? You found the perfect solution, in my opinion. I use this method for a few applications.

I would love to get some and try it, I just can't find any to get.

FWIW, Granger claims to have Chromic Acid......their item # 8FV43.

The plastic pipe tube is a really good idea. Checked a chart and the liquid volume is not very much, and as you found out, preheated solution works just fine. Good idea!

It's not bubba. I lot of guys do it this way!

It worked out better than I had thought it would. It also helped that while the mix was heating up I threw the op rod into the kitchen oven to warm up.(170 F. for 10-15 minutes) I snagged a length of mechanics wire into the tube to help remove the rod when finished.

I threw some pennies into my old solution because I had read that perhaps copper or other metallic contaminants caused the greenish cast. I just used the solution on a Stevens 620 and it came out a nice dusty rose color. So... I get to reblast and make a new batch of solution.
