Hi Stefan

I use photoresist because of through hole plating process
requirements. Only with this resist I can cover the holes after the
through hole plating (and of course for the plating process the boards
can't be coated with photoresist).

Apart of this, I can also achive finer layouts using the resist.

Just the reasons why I use the resist. As elsewhere mentioned I'm
using the one available from Bungard. I'm laminating it using an
office laminator (GBC 1200).
