Why should it matter how another builder chooses to finish his or her models?
I often use Alclad to replicate "chrome" trim on my cars and I use BMF as a mask when doing so. That's also very inaccurate, but in some situations, it's the best option to achieve the results I want.
Sometimes I don't even use clear coat. If the paint already looks the way I want it to, why mess with it?
When building a model, I don't like to limit my options. To say, "I always do this, and I never do that!" is to me, just plain silly.
