Can't be certain, even though we have a long gravel driveway. On the road we hear the occasional smack of a colliding rock, and the windshield already has four or five itsy stone chips. However, no tears in the 3M plastic, even tiny ones. It seems as if the bra material is pliable enough to recover its shape after being hit so long as there has been no tear. It appears to be pretty tough stuff.
So it's hard to tell the extent to which the mud flaps deflect damage as compared with the 3M bra-type plastic. Bottom line, using both types of protection the vehicle's paint is exactly what it was when we drove it off the dealer's lot.
BTW, I had the 3M installer remove the clunky factory stock clear plastic protection in front of the lower-rear wheel wells. Once that was taken off (aided by a heat gun), a significantly larger swath of 3M bra plastic was applied in front of the rear wheel wells.
(Had the headlights covered with 3M film while we were at it to prevent haze, cracks and dings. Everywhere else the 3M film adheres perfectly, but there is slight wrinkling on the 3/4" outer wraparound of each headlight -- not enough that I wouldn't have it done again, but those considering it should at least be aware of this.)
