Homebrew PCBs

One remark, please use respirator & gloves when handling xylene.
The stuff is 100000x more carcinogenic than we knew pre 1990.
I remember working in billboard printshops mid 80s and shoving my arms 
bicep deep into 55 gallon drums to clean off ink.
Wondering whats going to get me down the road.
