Well, they say the camera never lies, but in this case it does!
The fillets aren't really that even, especially the first ones I made towards the back, but here's what I do...
The fillets are actually very short chopped strands of glass - I couldn't find woodflour anywhere handy, so thought they would be pretty strong - posts by Jacques seem to be of the opinion that you can use them if you like - so I did!. Anyway...
I lay the fillet with a toungue depressor, as it's pretty fibrous, it goes on fairly easy. I don't worry about getting it too smooth at this stage. By the time I finish a 'compartment' it's just reaching the 'green' stage so I apply the tape immediately. I consolidate with a finned roller - it's got a diameter of about 20mm, so as you roll into the fillet it compresses it into a lovely round shape.
The two of us working together can fillet and tape a compartment in about 1 hour - we seem to have worked out a reasonable system - did twice as much today as yesterday...
