The Silverado mixes materials, and the repair plan has to match
A current Silverado is neither an all-steel truck nor an aluminum one. General Motors hangs aluminum doors, hood and tailgate on a steel cab, over a roll-formed high-strength steel bed and a steel frame — so one collision can put two materials and two joining disciplines on the same work order. The aluminum closures need their own tooling and abrasives; the steel bed and frame do not; and the two kinds of work cannot happen in the same dust.
GM publishes sectioning points, weld counts and adhesive specs for each body because the truck was engineered to fold in a defined order. We laser-measure the frame and cab mounts against factory dimensions before any pull, correct on the frame machine, then measure again — and both printouts go in your file. On a pickup, cab mount condition matters as much as the rails: a body sitting a few millimetres skewed will never close its doors evenly, no matter how good the paint looks.
The bowtie is a radar window, not a decoration
On most Chevrolets with forward collision alert and adaptive cruise, the radar sits behind the grille and reads out through the emblem area — a panel engineered to be transparent to the beam. A chrome-look aftermarket emblem, a bug deflector across the nose, or a heavily metallic refinish over that area can attenuate the signal enough to change how early the truck reacts to slowing traffic on the 401.
That is a large part of why our parts position matters on a Chevy. Anything a camera looks through or a radar looks past is specified as a genuine GM part on the estimate, the vehicle is scanned before teardown and after reassembly, and any calibration GM publishes for the work performed is completed before delivery. None of that is optional on a vehicle whose braking system is permitted to intervene on its own.
- Genuine GM parts specified for grilles, emblems and fascias in the radar path
- Pre-repair and post-repair diagnostic scans on every Chevrolet
- Frame and cab-mount dimensions laser-recorded before and after structural pulls
- Rear park assist and blind zone sensors function-checked after bumper work
Tricoat whites and reds: the hardest hour of a Chevy refinish
GM leans on three-stage colour across the range — Iridescent Pearl Tricoat, Radiant Red Tintcoat and their relatives all float a translucent layer over a base coat, and the finished shade is set by how many passes cross that middle layer. Two painters can work from the identical code and land visibly apart. That is a procedure problem, not a mixing problem, and the only honest answer is to test before committing.
Every tricoat Chevrolet here gets a spray-out card built with the same gun, distance and planned pass count as the vehicle. The card is checked against your panel under booth light and again in daylight, adjusted, and only then is the truck sprayed. Colour is blended into the surrounding panels rather than cut at a seam, and the work carries our lifetime paint warranty for as long as you own it.
