Depends of a lot of variables.
One, which grade of clear (most paint suppliers have several grades of clears), on what reducer was used, what booth was used and were the paint supplier's recommendations for reducing, air flow in the booth, temp in the booth, etc.
Then there is the "catalist" factor as most modern clears require a "hardening" agent (catalist) to be added in an exact amount. Many shops will cheat on this due to the very high cost of the catalist.
They think that they can do some other less expensive methods and obtain the same results.
Same may take place in an assembly plant, as each plant operates on a "profit" system.
Makes no difference what the base or color coat is to as what "color" is harder or softer, it's the clear that may be hard or soft.
Some base coats will cause light refraction that will make certain colors appear to be more prone to scratches ,marring, etc, however, that is all they do in regards to hard or soft, they have no real effect on that issue.
