HAIR!!!
I am using Squadron Putty to make some Hair.
I just sqeeze it from the tube and shape it with a #11 X-acto Blade. Don't use too much, it will melt plastic!
Looks a liitle too Clean-Cut for Gasser, so I made "Spikes", by squeezing putty right on his head and then pulling the tube back. I started at the back and worked my way forward.

That's a Good Start...
