To me, the trouble is well worth it if I’m not looking to fly the rocket. If I’m flying it, I would only prime, top coat, and gloss the rocket, without much sanding if any. Easy 1 week process.
Now on the other hand, if I want to achieve a smooth and very aesthetic finish for a shelf rocket, I would go through all the steps you could imagine to get the finish smooth.
I have trouble with CWF too, it seems that if you sand too much, loads of it falls out the spirals. I had some wood glue run down along my BT, where I had to sand down a lot.
As of now, I am currently on my 12th coat of filler primer with spirals still visible.
My only solution would be to redo the spiral fillets, sand, and re prime with filler.
I am planning on my next build to build the rocket, CWF the lug / fin fillets for a smoother transition to the body tube, and perhaps filling in spirals lastly, after my rocket has already been constructed
Quick question, are there build threads on TRF ? I would like to document my builds to help others out !
