Does anyone have experience with painted wooden front doors?

Hello everyone,

Does anyone have experience with wooden house doors? For example from Ruku. Steel frame, insulated core, etc. So not solid wood.
On the outside, a 5-layer mahogany veneer is applied and then the following paint layers:
Primer
Filler paint
Undercoat
Topcoat
2-component paint

Can something like this last permanently or does it have to be treated again?

.. depends on the exposure of the front door.

We had a painted wooden door for 50 years - it was repainted a few times during its lifetime.
