Renovation sofa in imitation leather / leatherette

Hello,

I would like to renew my sofa and stop the cracks that appear in the right of the most used seat.

While browsing the forum, I saw a product "renovator leatherette and black imitation leather" which made it possible to fix the parts which flake but it is apparently more on sale.

Which product would you recommend as a replacement? Is it the'black re-colouring agent for imitation leather living room' or is there a fixative?

There are also small areas where there are missing pieces of coating. I therefore wanted to use the "repairer scratch salon imitation leather / black leather".

Can I have an optimal result? and if so, should I use the repairer before or after the product that would fix the cracks?

Thank you in advance for your answers

Sincerely

Fabrice
