can you solder using the reflow oven? (might get too hot)
Get etch resist to NOT FUCKING FLAKE OFF THE STUPID PCB DURING ETCHING GRAAAAAAHHH! *rage*
RESULTS: Use Fe3Cl, not NaPS. All other attempts led to epic failage.
Tried a couple of curing temperatures (temp setting on reflow oven) and times, here are my results:
100 ðC
150 ðC
170ðC
180 ðC
200 ðC
4min
FAIL!

„OKish“ means the resist still flaked off, but stuck to the board relatively long.
An attempt to print on a pre-heated PCB and curing for 4min at 170 ðC gave the best results so far (though not perfect), but the hot PCB warped the plastic carrier beyond repair =( A routed aluminium carrier with integrated heating could work.
