@cavx In the US it is found in our chain hardware stores in the paint section. It is billed as an outdoor furniture fabric protector. Another option you might have would be something like amazon.jp
I found the pressure pack and spray bottle versions at Bunnings and the Rustolium at Autobarn.
Those really do look good. Is the belief that the color alone will filter the UV wavelength?
The blue dye will penetrate a few microns in. It doesn't go all the way to the centre. So it can't can't actually protect anything. It is more of a good looking, quick fix If the rubber is not UV stable and goes yellow, then these eventually will go greenish.
