Yes, I will keep the squadrons of bugs & flying insects [about to launch themselves any day now] out of my radiator assembly. On facelift 124's it is very very difficult to clean out the radiator properly, gunge collects, cars overheat and things corrode. Also I don't like flies hanging around the front of the car eating the dead flies whenever I'm parked for more than 5 mins, their acid can’t be good for the paint & attracts cats to pee, Grrrrrr!!
I'm hoping I can make something that can be cleaned with a hose, or unclip it and clean or replace it with a clean one. RoA is 42%, 304 stainless steel. I've got some at 29% and 39% too, trial and error, need to keep the bugs out of the rad, it is going to be a balance...
