Airfix C-47; Scratch another model and file under B (for bin)

I give up! The model has been niggling me since I started but after giving it a coat of matt varnish it has showed up just how rough the finish is, plus for some unexplained reason the areas that I used Johnsons Kleer for the decals are really prominent and something that has NEVER happened to me before;

So that's that! I don't intend to do anymore to the model other than use it as a test subject so sorry fans if you were looking forward to seeing it finished.
The other problem is that I am now reluctant to start another aircraft model due to the issues I'm having with finishing them.
