I recently acquired some old boards and am going to cut them up for a HcL and peroxide soak. There looks to be gold traces under the green varnished areas as well.
My question is, will the HcL get under/through that to loosen the varnished areas like it does with the exposed gold/traces?

Thank you in advance for any info you can provide. I am a beginner with this process. Last batch did not turn out as expected so looking to make the best of these boards.
