Review on Hooke Road Universal Bike Car Carrier: Quick-Release Alloy Fork Lock Alloy Bed, Roof Mount Rack for 1 Bike - Cross Bars Excluded by Brent Henderson

The finish is good as described but after a month in my rack the black color has changed on both front fork locks. One turned dark purple, the other brown. They don't look pinched and no longer fit on the crossbar of the shelf. I believe it's some kind of oxidation because you can wipe it off with elbow grease, but it'll come back soon and I suspect some of the fairing/paint/coating is peeling off because the rags turn black when rubbed. The discoloration doesn't seem to affect function yet, but it does look odd compared to the rest of the rack system.
