I heard about those metallic Sharpies that supposedly work really well for detailing TF's. I'd like to know, what colours are available, how well do they bond to the plastic, and are there any adverse effects that might happen to the toy? Also, I'd like to know more about those markers people use to detail the panel lines on Gundam models. Where do I find those? I ask this because I'm planning to maybe give some extra detail to Cybertron Vector Prime if and when I get him.
