I've use Mc Guires leather conditioning once before. Will this product increase the life of my leather? I'm working full time landscaping now and noticed that dirt is starting to show on it. I want to prevent cracking as well.

The meguiars will make it last, but dirt is a no-no. You're better off getting some covers ontop of the dirty seats.

that is what i would surely do too

One more question. If the McGuires treatment sat outside all winter in, say 20 below weather, is it still good?

i know my turtle wax has been through hell and it is still good

It will be fine in cold weather, but try to apply conditioner to leather that has warmed up, i.e. apply it in cold weather after the car has warmed up and been driven around for awhile.

what I have used in the summer for cheap seat covers when I am all sweaty is a beach towel. Tuck the top into the headrest and the rest will pretty much cover the seat. Its cheap and easy to take on/off.

i wonder if there is any way to get the "dirt" off the leather seats? Would a steamer work?

I used the Meguiar'* aloe cleaner and conditioner today on my leather during my lunchbreak. Made 'em look a lot better, been about 6 months since I've cleaned the seats. Just don't use Armorall on the seats (creates drying and cracking) and you should be swell.

Maguires is good stuff......

the best thing to do is take a change of clothes and change if you can before you leave work. I do everyday!!
