Source of UV Photoresist lacquer?

Brace yourself for the Price David.

Mega's prices aren't that bad - I've used them for years: http://www.megauk.com/pcb_chemicals.php - the immersion tin plating is excellent as it really protects your boards.

The UV coating I used was the Seno stuff: http://www.megauk.com/chemical-applicators.php - but I preferred the pre-coated boards - got better results that way...
