Hi Andrea,
I have never tried the method suggested so can only say "maybe, who knows?"
On the other hand, there are a couple of possible causes for your problem. The first is leaving the copper patina solution laying on the glass after it is "spent". Each brush load of solution has only a finite number of copper ions to contribute ot your patina. After they have been deposited out of the solution, the remaining "juice" is "Copper hungry" and will begin to pick copper back up again. Worse yet it will move copper around from here to there causing light spots and nasty dark blemishes that don't easily polish out. As soon as you brush copper patina back and forth a bit to get the color out, you need to sop up the remaining solution. I have found that spraying the dried area with ammonia brings out extra brightness, but you need to be sure to wash well after that with a neutralizer like CJ's.
The second problem can just be the wrong brand of patina. Super Brite works well for most folks. Canfield brand is best if you are looking for aa mottled antique look.
