Pressure washer removing paint

I was at the car wash last week and as I was rinsing the salt and snow off my truck I noticed some paint missing on the edge of my rear bumper. I thought this was odd but continued to rinse. As I got to the other side I acutally some paint come off! I have never had a problem like this with any other vehicle using a pressure washer. Any Ideas? Is this sort of thing covered under warrenty? Otherwise I might have to buy and ARB bumper in the spring.

 

isn't kind of cold to washing ur truck in kenora this time of year?? if your under warranty i would take it back to the dealer and let them know

 

i had that same thing on the front bumper cover.just a small(dime size)spot.i just backed away a little more when i do it now.went and got a bottle of touch up at dealer.

 

That would be rust prevention. I do that to my truck too.

 

Went to the dealer today and they wern't all that helpful. First they said it is not covered if it was done by a pressure washer (I didn't metion it was). Secondly, because it is an American vehicle that they would have to take pictures and send it to Toyota Canada for them to make a decision whether or not I would be covered under warrenty. I will take some pics and I will need some feed back on how hard it will be to touch up myself.
