I uploaded this to R3V a while ago but I thought i'd share this to fellow maxbimmer members as well.
A while ago, I was looking for a set of leather seats...and seller sent me those images..
So I brought them home. Front seats had fair amount of cracks..
Rear pieces are in pretty good condition
I ordered Leatherique kit from Leatherique Canada - they were very helpful and informative.
I brushed Rejuvinator Oil onto the seats several times until they stopped absorbing the oil(front seats took about 5 coats and 2 coats for rear)
After 2 days(leather surface got much more soft after that) I grabbed leather cleaner
and sprayed on the seats
I let it sit for 2 minutes and started wiping off. I had to use about 10+ towels to get them complete dirt-free..
After I cleaned & redyed the back seat
