Its after market, got it done locally but from an expert. A few already cut covers are available at shops that only need to be stitched, but those do not bring the finishing like this and leave a few areas visible. This was custom cut and stitched.
About layerings, the resellers in UK that sell this (polishedbliss, very highly reputed) have been keeping a good 10-15 layers with ease. I wont be keeping that many but may go for a couple more layers every 2-3 weeks.
I dont have a carnauba wax though
and I'd like to have a quality wax (p21s, dodo LF/WD etc) like my other collection but not at this time. So i'll have to wait.
