DIY PCB etching

[Theo]

Laser transparants work fine.
They are not iron-able, use photo sens. PBC material.

I'am very happy with black-out spray.
This dissolves the toner somewhat making the lines more black.
Black-out is supposed to be a special formula, but I think its just
transparant acryl varnish.
(smells, looks, feels the same and gives the same results (tested))

Cheers Theo
