Hi Steve and glad you like the Spitfire.
After I'd sanded the plastic to fit I finished the job with a solvent based filler. Looking at the picture I reckon I used the
Tamiya stuff. I'm not a fan of the Squadron putties but there are plenty who are!
The camo on the spit was masked with Blu-Tac. Because I wanted a fairly tight demarcation I pushed the "sausages" fairly flat and then filled in behind them with tape. I try to spray at right angles to the surface of the model which then gives a fairly consistent and sharp(ish) demarcation.
The kit was the Pacific Coast Models (PCM) 1/32 Spitfire XIV. There's a build here which explains more the trials and tribulations of a limited run,multi media,but very nice kit
