I treated my black Novillo leather mid june with....
"Leatherique Rejuvenator oil"
It must be 25°C to open the pores of the leather, then you can apply
the rejuvenator oil, downside is ,it gets very hot in the car !
I parked the car 2 days in the sun (windows closed)
I applied these 100% naturel products with my bare hands.
Only downside is the evaporation of the Rejuvenator oil ,it leaves a greasy film
on the windows.
This is the best product i ever used for my novillo leather !
Now It's 5 months later and my leather looks still perfect !
And I can see and feel the difference !
Would I do it again ? Certainley ! I'm pretty sure this is the best product for our leather interior.
