Cheap solution dont do it . <| sep |> New leather , sure , but it will still get porous , especially with wear and tear like on side bolsters . It ' s definitely not hermetically or permanently sealed off . Auto leather is so thin and flexible and its coating moreso it will eventually flex and show cracks or pores through stretch . Personally , I ' d encourage conditioning on coated leather that isn ' t really new at worst it does nothing , at best any pores exposed , microscopic cracks , stitching holes , etc . will absorb it , and these would also be areas that are most likely to dry out and be susceptible to further stressflex . Even if mostly useless , I figure so much of detailing is better safe than sorry that I may as well do it . That said , you ' re right conditioner isn ' t needed very often or perhaps at all if it ' s being cared for properly . Another reason to use a protectant to prevent that damage .
