Im in the process of decision making reguarding a total repaint. So Ive been trolling every BMW pic for inspiration and came accross this one -

It appears that the g/box, rocker covers etc are all painted in the same 2pack paint as the frame & tank.
I was under the impression that anything other than hi temp paint would not be suitable for engine, g/box, diff, timing covers etc.... and will blister & peel.
Anyone had any experience painting these components or have feedback as to how well such painting has aged ?
