2. Recall that the interior of the vehicle must be checked for damage.
3. Recall that unibody-frame measuring straightening equipment is used to help determine damage.
4. Explain “total loss”.
5. List two ways to determine vehicle damage.
6. Explain how to check for damage in a rear end collision.
7. Explain how to do a visual inspection of the underbody.

Decide When To Repair/Replace Body Parts

1. Determine when to replace parts

Prepare Estimates

1. Recall that an estimate is a firm bid good for 30 days.
2. Explain “flat rate”.
3. Explain “labor time”.

6. Recall how you can manually override a program.
7. List the features of an estimating program.

Remove Structural Parts

1. Describe structural parts.
2. Explain when to replace structural parts along factory seams.
3. Recall that spot welds hold structural parts together.
4. Determine steps of the repair.
5. Recall that before removing parts, usable parts are pulled into alignment.
6. Explain how to separate panels.
7. Explain how to prepare the vehicle for new parts.

Install Structural Parts

1. Recall that a measuring system is used to align new parts precisely.
2. Explain how to treat structural parts.
3. Recall that all welds should have full strength penetration.
4. Identify that weld-through primer is applied to bare metal.
5. Identify that locking pliers/screws are used to hold parts in place.
6. Recall that a welding respirator is needed when welding.

Section Structural Parts

1. Explain sectioning.
2. Explain where to section.
3. Describe lap joints.
4. Explain where an insert is placed.
5. List two requirments of sectioning.
6. Recall procedures before final welding.

Section Rails

1. Recall that when sectioning rails, all damage is removed if it cannot be straightened.

Understand Why Damage is Measured

1. Recall that measurements help the estimator calculate the cost of repairs.
2. Recall that measurements are taken from reference points on the vehicle.
3. Explain why the frame/unibody is designed to crumple.

Distinguish Types of Damages

1. Explain sag damage.
2. Explain mash damage.
3. Describe diamond damage.
4. Explain twist damage.
5. List 2 reasons why measurements are important.
6. Describe sideways damage.

Understand Dimensional References

1. Describe the datum plane.
2. Describe symmetry
3. Explain how a vehicle is divided.

Use Measuring Equipment

1. Explain how a laser measuring system works.
2. Describe a gauge measuring system.
3. Explain how self-centering gauges work.
4. Identify when to use a strut tower gauge.
5. Describe a robotic arm type measuring system.
6. Explain real time display.
7. Explain how most computer measuring systems give readouts.

Evaluate the Surface

1. Explain the need for prep work.
2. Recall that on previously refinished vehicles pain thickness should be measured.
3. Recall the thickness of OEM paints.
4. Recall that the clear cost is about 2-4 mils thick.
5. Recall that when repainting the maximum paint thickness is 10-12 mils.
6. Explain how to remove excessive paint film thickness.
7. Recall that a good paint job is only as good as what is under it.

Perform Part Removal

1. Explain how to prepare a rusted surface for new paint.
2. Determine whether to remove or mask when painting.
3. Explain how to remove labels, stripes and decals.
4. Describe how to remove stick on emblems.
5. Recall that it is best to remove surface mounted parts when possible.

Sand and Scuff

1. Recall that 220 grit sand paper is used to feather edge paint.
2. Explain how to avoid sand scratches.
3. List 2 treatments for bare metal areas.

Mask

1. Recall that vinyl tape will avoid a thick lip or edge of paint.
2. Recall that paint masking is done with gold or plastic sheets.
3. Recall that back taping is done to prevent a hard, sharp painted edge when the tape is removed.
4. Recall that masking rope can be applied behind panels.
