I used this. Paid $20, have seen it for $15 since. I'm not affiliated with them or anything, just gave it a try on new car. Hardest part is letting car sit for 24 hours to let it cure.

Are your plows pretty clean and well painted yet? If you're worried about snow sticking and the plow faces are fairly smooth, I'd be curious how ceramic coating would work. People have had good luck with the cheap versions of ceramic coat, specifically this one.
Took advantage of the quarantine and ceramic coated the whole car on my own this weekend. Used this from Amazon: https://www.amazon.com/dp/B082VT2SZQ?ref=ppx_pop_mob_ap_share
Yet to see how long it’ll hold up, but I’m every satisfied with the results right now. And before people freak out, no that is not a V8 Biturbo badge on the front fenders 😂
Love it! Great job! Btw, I used ceramic coat on my jeeps faded plastic and holy heck it worked amazing! I highly recommend.
