I would like to ask the owners who has some miles on your outlander.
Do you have much paint chips on the front bumper?

I had planned to install a 3M clear bra, I noticed the lower part of the bumper is black plastic and the painted area does not start until 17" off the ground.

That's very high clearance compared to a Evo that sits maybe 6" off the ground.

So I am thinking rock hits on the bumper on the Outtie may not be that frequent, so want to know what you guys think.

 

Yes, I have a few. Not really that bad, but you can't avoid it. I have quite a bit of thread left on my tires and I see a few small rocks caught in the grooves. When that happens some of the rocks are going to get thrown off and hit the car behind you. FWIW I've read good things about the DR Color Chip paint kits to fix those small chips.
