I want to make a general guide for masking the missing toner on copper clad after toner transfer.
The masking methods I know so far:
- Permanent marker (some say it doesn't work, I am intimidated by it so I'll use extra cover)
- Nail polish (very reliable)
- Paint (I don't know which type, I would like to learn)
My story: I am using the acetone method to transfer toner (iron didn't work) and I have a small part of missing toner. The permanent marker pen sometimes removes the toner accidentally when it is rubbed and it is frustrating. I am planning to buy nail polish but I wanted to ask before doing so.
