I actually don't fully agree with mounting bumpers to the shield..... It depends on how close the deflector is to the hood.
I say this because I had a deflector at one time and stuck the rubber to the deflector. In certain wind and speeds, the bumpers came in contact with the hood and actually rubbed through the paint over time. Mounting directly to hood will prevent this, and if done with the correct adhesive will have very minimal impact to the paint.
More .02 opinion
Deflectors are like floor mats and side window rain deflectors not all up to the same standard for appearance and durability. I agree, bumpers on the hood if the deflector is so flimsy it deforms that easily under pressure; I've seen some of the thin gauge cheapos; won't put them on my hoods. Must have installed at least a dozen by now, and haven't put a Weathertech on yet that has ever bent enough under heat or wind load, nor marred any paint below. On the Traverse almost two years and hasn't touched the paint on the hood yet.
Had to install another brand side window deflectors on my '19 Silvy because Weathertech hasn't manufactured ones for the rear windows as yet. Even though this is a non critical area for flexing, as soon as the heavier gauge Weathertech in-channels come out for the rear, the others are going into the trash.
