Hey Stuart,

Yes this is going out! Sounds like it may be part if not the whole
problem. I am going to back the light out or down until I know I
have a safe space to coat the boards, and then if I still dont get
good results I will switch to sunlight just to prove to myself that I
have a good source of UV.

Right now it does seem like the problem is over exposure rather then
under and it may be the bug light zapping them before I ever even get
going...

thanks to all who have replied and helped by pointing out the
details, I will try it again with the new techniques and let you all
know how it goes. Though its at least a day between each trial.
