So, I am back with new info.
I checked recently the paint thickness of my JAZZ/FIT and could notice that it is between 80 and 90 micrometers. Minimum (told by the Honda manager is 80). But I also checked some other cars and they had 130-140 micrometers. Those were european cars.
I also visited the insurance valuer and told him my investigation results. He said that all japanese cars have the same pant issue - I can't tell for sure, its his opinion.
Then I also visited my Honda dealer and there was also the boss of a paint shop (he is official paint job maker for Honda and Mercedes in our town) and I was told, that all new colors really are on water basis and that both, Honda and Mercedes have near the same paint thickness (80 micormeters). I want to chack this. It might be true, if so, then the only problem i that the final paint coating is too thin (color coating).
Thas about it and I really want at least the exposed areas to get fixed. But it is hard so far. I wonder what will come out after winter -> with my hood and front bumper...
