I can help with the mini stripping.
Pop to Tesco, ASDA or.where ever you feel like and pick up a bottle of fairy power spray (green spray bottle)
My method is putting my minis in a plastic tub then spray with the fairy and put the lid on the tub, leave it 30 mins.
Take a mini out scrub it with a cheap toothbrush until all the paint has gone.
Soak it in water with washing up liquid, and give it a scrub with a fresh toothbrush, just to make sure there's no vanish left.
Then just leave it to dry.
I don't know how you are priming them, some primer comes off some doesn't.
