How can a steel panel be identified?
Check with a magnet
Scratch the surface
Check for signs of flaking
Tap it with a hammer
How can a 1k and 2k finish be identified?
Use compound and look for discoloration.
Ask a colleague.
Carry out a solvent wipe test.
Check with a magnet.
What can be used to minimize the amount of dust when flattening body fillers?

To prevent a feathered edge
To prevent a curved edge
To prevent a hard edge
To prevent a straight edge
What is the main purpose of a primer in painting?
To provide a smooth surface for the paint
