Removing ( Refitting ) Move all fouling parts.Check if any of the connected parts are deformed by checking body alignment dimensions. Use appropriate measurement tools (reference rigs, templates or gauges).Straighten the body if necessary. 1. Use a vibrating cutter with suitable blade to cut the sealant (1a) between reinforcements (1b) of roof panel (1c).2. Remove the paint from around the edge of the roof panel using a rotary brush to reveal weld spots. 1. Use a chamfering machine to crop weld points on the front and rear edges.2. Drill out weld points on the side edges.3. Use an oxyacetylene torch and steel brush to unweld the braze welds at the corners of the roof.Use a chisel and hammer to remove spots ground previously.4. Remove the roof panel from the car. 1. Straighten the roof panel seat flaps using a mallet and profiled stake.Use a grinding wheel to remove the weld spot residues.Use a rotary brush to clean treated areas.Apply the electric weld paint finish.
