Probably the least time intrusive part of working on front end and ya left it off? Hate to say but will probably act like a tunnel for the rest of the under carriage as well which some parts are barely if at all rust resistant.

What about the parts made from chocolate and cotton candy? Won't they melt?
While the undercarriage shields offer protection from the road, I think they are also provided to reduce road noise and improve the aerodynamics of the car for better mileage. I doubt anything will melt.
Just took mine off after being attached for past 6 months. lots of granules, smaller than pebbles, larger than sand. If you park in the same parking spot, you might use the opportunity to place a material under the 'open' engine areas to see if you have an undetected leak. the panels may contain small leaks. You can clean them if necessary. Use common sense for where you drive and how long off.

@CaliBenzDriver On my model, do you know what other electrical/critical components might be positioned low in addition to alternator? I want to wipe, then carefully hand spray bottom with de-greaser/de-oil without damaging any components. Hunting for a leak. TIA.

I do! Mercedes has exactly what you're looking for:
our car feature its most important connection: the main GND strap.
You need this to be as clean or better than battery connections - It is located, near tranny flywell and cats under the car.

You're right. Maybe it's just me but I always struggle to put this piece back on.

While evaluating an ML for purchase, I noticed the missing skidplate and asked about it. The owner mentioned he did not longer had it (a minus in my book anyways), and I was worried about the electricals. Once I scanned the car with XEntry, a few error codes for shorts were there. Asked again about recent electricals, and not surprised: new AC and alternator in the last two months, coincidentally during raining season here in Florida. You can guess I passed on the "opportunity".
So what else besides the alternator? AC compressor and electrical steering if you have it.
In the meantime, avoid water puddle at medium speeds since the splash from below may short an active electrical component. Regardless of how much water-proofing the connectors have, the wire is coming through so can the water.
Yeah, I pretty confident that the engine compartment paneling is just to help with weather proofing the engine bay. For a short time it's likely that it won't cause issues but I wouldn't keep them off for long since it will expose a lot of components to a harsher environment them they were designed for.
I don't think the US spec has the undershields installed (code 481). It's a standard in countries with bad roads (like mine) and it's a big and heavy metal plate covering the botton of the engine.

All our MBs from 2008 up to 2015 have the under shields. I think option 481 is a legacy option
