Theirs a lot of misinformed sh!te on this thread...
The blue Mk3 tailgate is nothing more than "Recessed" or "Tunneled" and has been executed with very little imagination... the misinformed would say its been "Frenched" its not.
"Frenching" is to recess a headlight or taillight in a shape that resembles the collar of a shirt... ie, the lamp would be where your neck would be!
A tailgate that has had No plate recess removed, and perhaps swage lines ironed out, has simply been "Smoothed" or "Decked" this is definitely not "Frenching"
