I actually already have Warbotron WB01. I decided to get the CW one after and paint him up just for fun. I wanted to make them look like real war machines, dirt and all. Plus CW toys are really cheap and virtually have no paint on them at all.
All done with my iphone using an app called Facetune. Use the tool that shows more detail and select the saber blade. Just run your finger over it. Pretty easy. That is the real light coming from the attachment. Works pretty well.
I was ever so lucky to obtain a custom cat walk created by a good friend on the forum here. It is from the first encounter scene between Bane and Batman from the Dark Knight Rises. I think it came out pretty awesome. My Pics.
