i soaked my kit in isopropyl alcohol for to days and im scrubbing it with a toothbrush, but it´s not really coming off :( I primed the kit with a spray can primer from vallejo and painted it with cheap acrylic based "airbrush paint". can i use aceton from the hardware store for removing the paint?
Many do recommend simple green, but it is not available in my country :( (Germany)
