Is Wax Frame Coating the Secret to Success for Chevy Trucks?
But waxing a frame accomplishes essentially the same thing. The issue that BTBRV takes up with waxing is that it’s an old and potentially inferior process. “All other American truck manufacturers have moved away from this process because it’s not a very long-term process. You can go underneath a GM truck and scrape your fingernail against it and actually remove the wax coating,” he says.
But how many people actually do that? And if this is the case, wouldn’t rocks and other road debris quickly remove large chunks of this wax, leading to rust within the first couple years of ownership? So far as we know, this hasn’t been a widespread problem on GM trucks in recent years.
BTBRV goes on to note that new Chevy trucks have box frames, which could also magnify this problem. “Box frames can trap more dirt, mud, and water than an open C-channel frame.” He points to older Chevy trucks with C-channel frames, which had a tendency to rust. But so did pretty much every brand of truck back in the old days.
Obviously, our host makes some valid points here. But in reality, we’re not seeing an influx of newer Chevy trucks with rusted out frames on the road. Plus, the fact that they’re continuing on with a tried and proven process has to count for something. And after decades of honing their frame building process, it might even prove superior over those newfangled methods in the long run!
