Case Study - Rusty Truck Frame

Customer arrived with a rusty truck frame, requested it to be repaired and repainted as necessary.  The technician disassembled the frame of the truck to prep for the sandblasting. The frame was sandblasted down to the bare metal, to remove all of the rust. The frame was washed and dried in preparation for painting.  The frame was painted, both inside and outside with the black frame paint.  After the paint was dry, the truck frame was reassembled.
