In the game, by default, you can choose (underneath the color palette) between flat, semi-gloss and gloss textures for your aircraft parts. However, i´ve seen several planes made by people that have the cockpit glass and other parts with reflective texture, they look like a mirror, even you can see the landscape of the islands reflecting into these parts...

My question is: How can I do that?

Because, the closest that i can reach is gloss, but "gloss" is not enough reflective, too fuzzy.

Is it a special texture that only can be got using external programs or something?
