Nice looking grille mod. I wish Toyota put in a finer mesh in the first place. The wide spacing is useless.
I was so plagued with radiator bugs this spring that I installed nylon window screen mesh on the front surface of mine. I wanted a flat surface to be able to clean it with a soft brush and not have to dig out petrified bug carcasses with toothpicks from all the nooks and crannies if it was installed from behind the grille. Plus the wind pressure keeps it place rather than having it bow inward like a sail if it was attached on the inside. After 2+ months and many high speed miles it’s still in place and working well.
Here’s a link to some more details:
