IMHO, the texture of the LineX allows the higher gloss of the hood insert to still cut down on glare. I've noticed NO difference in glare before/after the insert was coated.
He didn't line-x the insert, some other kind of paint/coating. I am Riff on this one, it doesn't 'fit' with the Line-xed cladding.
I can see where the textured stuff would cut down on glare, no smooth surface to reflect off of.
