How durable is leather repair and refinishing?
Much depends on usage. Just as the factory leather wore out over time, the repair that I perform will also wear over time. But I've found that the refinish lasts about as long as the original finish.

How can I extend the life of my leather interior?
Leather surfaces have two main enemies: Sun and friction. The UV rays from sun cause discoloration, drying and cracking of most vehicle interior surfaces. Reducing sun exposure will add years of life to your interior.

Friction from sliding in and out of your vehicle reduces the life of your seats. If you have a truck or SUV try to use the running boards (if installed) when entering and exiting the vehicle. In cars, the outer bolster of the seat back takes the brunt of the friction. Try to minimize how much you slide across the bolster by moving your seat back before entering the car.

Do cigarette burn repairs wear well?

Much like leather repair, much will depend of usage. In high wear areas the burn repair's appearance will diminish with time.

Can you repair dash boards?

Yes. But if the crack originates from a vent or the windshield due to age, it is unlikely the repair will be durable. Cracks from other damage hold up quite well.
