Just thought I would list one of the many mistakes I have made and learning from during building. Do not silk span over the fillets.  Add them after covering the plane.  If you silk span over the fillets you will get raised bubbles when you spread on the dope.  I had to cut these bubbles away and redo the fillets.  Any other advice on fillets will be appreciated and put to use on my next model.   

Watched the youtube video and want to thank you for the excellent tutorial.  I hope to learn something by trying the superfill this way on my next build.   Phil
