Homebrew PCBs

I have done lots of photo resist stuff in the past.
Pre 1995. But in about 1997 I picked up some supplies
at a local dealer that served the retail/hobby
community. The stuff I got from him did not work well.
But beleive I did not expose it with a UV lamp. It did
not say it needed UV. And I think it may have been
DATAK stuff. 

I have not done any PCBs since then.

But next month I am going to try the stuff from MG
Chemicals. Since I have to buy more board stock I
might just as well buy the MG pre-coated stock. I only
have one more un-cut 4X6 1/32" panel sot that's no
great loss.

I am reluctant to invest much int the TT process as I
already have an investment in the photo stuff. All I
need is the board stock and developer. Everything else
is the same.
