Fitting a custom mesh grille

[AlexNet0]

I destroyed my stock bumper, so I ordered an aftermarket from Garm, I was wondering what the best way was to mount the custom grilles im cutting from black wire mesh (pending prices) to the openings on the bumper (fiberglass)

Just wanted to get a good idea so when it gets here I can get the grilles in and prime it without too much hassle.

If this is posted somewhere already, forgive me, I searched some but probably not as much as I should have.


Thanks
