That's a good article. I went and read it again. He's a little short on details with the tip about putty. Which putty, which kind of polish remover? Based on the date of the article, I'd guess he used Squadron Green, and the smelly kind of remover, pure acetone.
A more up-to-date method I like would be Tamiya Gray putty mixed with Tamiya thin cement in the green capped bottle.
But... I also like what he ended up doing. Most of the airliner kits I build have decals for the "glass". That way the parts can be installed and smoothed in nicely. And the frames on clear canopy parts can be overscale and in particular raised way more than real.
Having your question in mind, when I opened the article to read it, I looked at the first image of the nose area and thought "wow, that worked". And then read where he painted it.
My biggest grumble of the kit is the open gear wells. Too much work to fix.
Keep us posted on your build.
