Homebrew PCBs

i dont think anywhere uk wise sells anything that strong without lots
of paperwork, if it could etch into brickwork etc, you would probably
need paperwork just to move it on the public road.

I tried biodiesel, if I got waste chip cooking fat from the
restaurant, I'd need paper work for waste transport....

UK has gone mad, anything to make a profit from the public, as all
bits of paperwork will cost money.
