Hi,

Does anyone have any suggestions on what I should buy to refurbish my lightstone leather seats? There's no tears but they're all cracked and generally looking old so I'd like to bring them back to looking their best.

Thanks.

To get them looking good is a fair bit of work. Have a look at post #233 on this page

I used Liquid Leather products- not cheap but really good stuff.
So, here's how I do it...
Seats out. No need to dismantle. Only reason I did was to sort out some seat heater and mobility issues.
Steam and scrub with fine abrasive Scotch pad (Care and finesse needed! There are air bags in the side cushions and you don't want to abrade the leather too much. Practice on a bit you won't see)
Clean with Intensive Cleaner
Fill cracks with Aquafill
Mask up piping
Airbrush as required with Scuffmaster dye
Airbrush with Sealant
Easy huh? Nope, it's time consuming and you have to be meticulous to get good results.
