ANother thought I had about using the photo-resist boards was the
potential for another problem that I don't know if there is a work
around or not.

If you expose a board and the exposure doesn't work out as planed,
it is then ruined isn't it?

For example, with toner transfer, if it turns out bad, a missing or
pitted traces or whatever else can go wrong, I wash off the toner
and do it again and again till it is good enough for what I need.
The only loss I have is time and paper.

However, from an ignorant point of view ( I have never tried this
process), if something goes wrong, the board can't be used again in
the potoresist process can it?

Also, as I don't know what things look like along the way, can you
see the traces with the resist on them after developing? If so,
what does the developed photoresist look like?

TIA
