Can you insulate the primary coil of a Tesla coil? Answered

Hello,
   I am trying to build a tesla coil using a new design relating to a thesis paper I am working on. Due to spacial restraints my primary coil will be close to the secondary coil. I know I have seen others use insulated braided copper wire as their primary. I want to stay with 1/4" copper tubing if at all possible so I wanted to ask what affects it would have if I used heat shrink tubing on the copper tubing. I am aware the higher frequency voltage runs along the skin of the tubing since that is least resistive at that point. A for the power and caps I am using the following: three NSTs of which two are 15kv @ 30 miliamps and one 12kv @ 30 miliamps, 13 CD 2000VDC @ .15nf caps on each 15kv NST and 10 of the same caps on the 12kv NST. The spark gap is static for now.  I want to prevent arching as much as possible in the small space. Any advice is greatly appreciated. Some of the information relating to the thesis paper I cannot release due to a serious concern of being scooped before publication. 
Thank you. :)

Using heat shrink on the copper tubing of the primary would be fine. It will not have any adverse effects on the operation of your Tesla Coil.
