I bought some uv set solder mask http://www.ebay.com/itm/New-10cc-UV-...-/371198380554

these are the instructions I received
Features:
100% Brand New
High Quality
10ml UV green paint.
Features with quick curing.
Insulates printed circuit board against shorting and arcing.
This paint is used to protect PCB traces from corrosion, moisture.It is also used for repairing PCB after soldering, rework.

Specifications:
Color: Green
Syringe Length: Approx. 10 cm
Material: Paint
Capacity: 10ml / 10cc

Usage:
Apply paint on your PCB.
Spread it on the PCB with covering the transparent mask film.
Expose it under UV light ( or sun ) for a few minutes.
Wash away the extra paint by gasoline or oil base solvent.
the trouble is that the mask sticks to the solder mask overlay far better than it does to the pcb, I think I need some sort of uv transparent film between the overlay and the board .

does anybody know of something that works ?
