Hi all! I'm pretty new to airbrushing and art in general. My next piece i want to tackle will be on some sort of black medium. What's the best surface for this if wanting to effectively erase? I went to my local art supplier and they didn't seem to have any clayboard or YUPO paper in black Can I just base coat something in black or will that make erasing (and erasing to far) a nightmare? Thanks in advance!
