Etching time

So here I am back to this photoetch plate.I have to reckon that the French product is -well-somewhat better than theBritish one, more sensible, but has a great downside it's that the varnish ituses is also way more fragile (look at the big cut traces on the plate), sowhat to choose?..

I have French stuff right now, so i'll use it, but how I have to be ultracareful with it when handling!
Sorry no pics of the actual etching, but i had to dip the fret into an etchingtank of my own build, and after 1 hour in the ferric oxide, I got that (below).Yep, that should be enough for my f-105 :)
