I was commissioned to make this 12 inch Crying Freeman few years back using Hot Toy Muscle Body. I had make some research and discovered that we can actually paint tattoos on rubber muscle body by using '
Citidel Paint' It looks like water base paint but has very strong bond on almost any surface. I think u can use this method to paint tattoo onto normal 12 inch plastic body but u will have to paint at least 5 layers or more on each and every lines if u are painting on rubber surfaces so that the paint will not peel off easily. As for how to put the tattoo sketch onto the body, u can either do it with free hand drawing(if u can draw well) or u can actually photostat the picture(preferably black & white colour) onto transparency and then keep on rescale the picture with the help on the photocopy m/c until the exact size that fits nicely onto the body area where u intend to position the body. Then, trace it onto a tracing paper with a pencil(remember to flip the image b4 u transfer it onto the tracing paper). Next, shade the tracing paper black with your pencil, place and hold it onto the body by using scotch tape and trace the picture onto the body. Lastly, u can start outlining and paint the tattoo picture. Here are pics of the tattoo paint work I had done for this 12 inch Crying Freeman Custom. I hope all these tips can help. Cheerz...
Best Regards,
