Thanks so much for comments everyone, always appreciated.
I suppose I have had a builder's block for a year or so, certainly I have an ongoing reluctance to get into the spray booth, which is why I'm doing models that don't need painting at the moment. Painting is always the hardest part for me and my success rate is probably under 50%, too low to be thoroughly enjoyable.
I'm now working on an AMT pre-painted 57 Chrysler and a Revell Impala HT, whose white plastic has been polished.
