Hello! Glad I found this thread. North of your border (Alberta) I was quoted 1100 for the matte black PPF on the rocker panels of my '23 silver Classic just last week... Which seems ridiculous. I was also told by the company that quoted me I'd be lucky to get 2 years as I spend a bit of time on gravel roads every fall.
I had a 2010 TRX, that I just sold for my new truck, and had the rockers sprayed with Line-X rock guard when i bought it.
It lasted about 7 years then began to rust from the inside out and eventually peeled everything from the bottom up. No warranty on rocker spray as they state it rusts due to water/ salt eventually seeping in.
I've thought about going the distance and masking, sandblasting then applying primer and Steel-It Epoxy coat so I can just touch up any rock chips as required.
I would be greatful for any thoughts or suggestions!
