Kitchen Cabinet Refinishing Nightmare...Help Please!!
It's hard to tell because of the camera flash, but I think they look good.
Try photographing them in bright indirect light with the flash turned off.
You can re-sand and re-stain if it really bothers you, but they'll never have the factory finish that you seem intent on.
You seem most bothered by the difference in shine between the different doors, but this will be most affected by the finish of the poly, which will help make them more uniform.
I think you're doing well, don't get too anal retentive about it.
When they're all hung, you won't be comparing each door to one another so carefully, they'll take on a general overall appearance.
That's a vintage door style, so they should have some character.
Keep going, you're doing well.
