Aoa Folks,
I had a question about what to do about rust developing on the car underside. I asked few car detailing workshops and they recommended Gravitex Upol. Some also suggested rubberized coating, which I believe is different from Gravitex Upol, but I read online that it can fasten the rusting process in some cases.
Here is one example of a workshop doing the Gravitex Upol undercoating.
Here are some pics of the car I plan to undercoat:
