I had the decals on my 09 that a had for 16 months then traded it in for the 2014 I have now. I washed the car mostly by hand and they never came off. I did go to the car wash with the hand operated pressure washer and it didn't come off ether. I got the car with them already on the car so whoever put them on did a good job too. Hope that helps. Also they get a lot of attention from other drivers.
Great. Thanks for the info. I'm thinking about adding them. They do seem to set the car off a bit with out being over the top
I had them on my prius c. Took my car through automatic car wash once a week and they never came off. iPad ?
