I can show you my painted bumpers compared to the factory ones,
it's quite obvious my bumpers get way less road rash, rock chips than
the factory ones. That's why I use epoxy primer on them.
It's a big difference that my customers really like.
I agree with you, baked clear or unbaked clear. Unbaked clear will cure to the same level of hardness over time as baked clear. The reason for a bake cycle is productivity and nothing else. If the OEM could keep the assembly line moving as fast without a bake cycle they would implement that procedure immediately as would any Body Shop. The cost of running a bake cycle is extremely high and insurance companies sure don't pay extra if you have that cycle.
One reason your bumpers with stand rock chips better than OEM is the epoxy primer, Epoxy is much more flexible and creates a cushion between the plastic and the top coat.
