I tried the spray photoresist a couple of times and the problems are getting  a uniform thickness, and dust.

Same here. Dust was the killer for me.
Good enough is the enemy of the best.

The only thickess-related problem I have is, that the paint tends to gather around the edges of PCB and it's not very flat there. You can spin the PCB (using i.e. pc fan) to improve the lacquer distribution, but this is only good for on side and obviously rather messy.
I love the smell of FR4 in the morning!
