Just keep in mind that leather that has tears or cracks will not look much better after the dye process. I think one can buy a product to fill up the cracks but not sure if it is available in SA. Google is your friend in this regard. Iirc, i think i have seen something advertised in the UK to fix the cracks. I have a very cheap compressor and even cheaper spray gun that i use. Adjust the compressor so the pressure is regulated to about 20psi for the best result. Also, Google how to use a spray gun/how to spray if you haven't done it before. Actually very easy on upholstery. I have a highish table on wheels which i cover with a piece of plastic and i remove the seats from the car and put them on the table when spraying them. Works like a charm! When it is windy i work in the garage with some strong lighting and the table on the wheels is nice so one can turn it for best lighting. (Move the cars out of the garage if you are spraying inside)
