Its a rust proofing bath that ensures the entire steel body gets protected. The whole vehicle goes under and is flipped over so ever little corner gets treated. After this step the vehicle is primed, inspected for flaws where some filler or extra sealant is applied (@ 2:35) and then painted by robots. After the painting step you see the workers do another inspection under special lighting to perform some light touch up with buffing tools (@ 4:08).I think the part where they drown the SC in the vat of whatever that is, tailgate and all, is very interesting!
What kind of issues did you have?I wish they focus on quality when building this truck. This is my 2nd Hyundai and I‘m noticing quality build issues that I’ll need to see if the dealership will correct. You’ll never notice until your excitement ends and really look.
