Another breakthrough:

You get a PERFECT component outline transfer if you clean the board with
this abrasive-type kitchen cleaner.
No clear laquer needed.

It polishes away the ugly paper residue and gives a beautiful finish.

I also discovered that surface cleaning and paper handling does not matter
very much with toner transfer of the component outline.
If you use doublesided boards the epoxy surface is nicely rough after
removing the copper
and it adheres very well.

Aligning is a bit tricky, but i first place the component outline paper on
the bottom
of the pcb, where i can easily align it with the copper image.
then i draw lines at the edges of the pcb, cut out the paper, place it on
top
and fuse.
It does not cause bad results here if you touch the freshly printed image
on the paper.
much less critical...

I'd say the looks are well worth the extra effort.

Now let's hope the baking tomorrow will not ruin the beautiful component
outline...
