I recently purchased Argon, I wanted to install through the alternate installation though via. The question isn't about soldering, i noticed on the wii chip (D2C) there is two versions. One with the Via opened and another one that is closed with laminate(I think), of course i have the closed one . I heard i can use a fiberglass pen to clean the laminate that covers the holes. Or is there any chemical i can use to remove the layer off the via.

Thank you
