Echoing Brians statements on the dremel! If you have any questions about dremel work feel free to ask. Also bit choices are important as is the speed in which you use them. If you are burning or melting the plastic at all slow the speed down. Thought I would throw out a few basic things.
Love seeing these new customs and all the sculpting. Can't wait to see your Gregor come together. I have tried a few things on the digital camo and was not real happy. A friend told me another technique to try so let me know if you are interested.
