RE: TF Spitfire build
i think most modelers who want a realistic finish go with glassing and painting. that's my plan. there have been many threads on how to glass and paint lightly. practice on another model before you do a heavy-prone plane like the TF. i did my first practice on an OK models P51 and it came out just 2 ounces heavier than published range. you'll get lighter as you build more.
