this is how you repair a lead acid battery
Bought some seats on eBay. They were a little scuffed and stained, and the leather panels were baggy / sagging. This shows the process of hot air gunning to remove the bagginess and recolouring to remove the stains. This was a first try and the hot air gunning without proper instruction – treat with caution!
