Title. Have invested a total of 6$ into a roll of bugscreen to slide in behind the slots. Mounting is the only hang up. No way in hell am I gonna go through taking off the grille, i despise the rust issues this thing has given me already. So what I've been thinkin' is either an epoxy, which would be hard to apply back there, or drill 3 holes a side and get some zipties in there. The ties would be more secure I feel, but dunno if I wanna go through sheetmetal. And the epoxy would just be difficult to find a way to reach in there and apply enough at good points for it to be secure.
Anyone else have some groundbreaking ideas? I'll be sure to pop up some pics of the process when all is said and done.
