www.griots.com has a lot of good car care products as well as stuff to enhance the appearance of your garage.
For flooring, I am going to have a company that does colored concrete flooring do the work. They can make your floor look like tile, wood, marble or whatever. They can make the finish as glossy or dull as you want and even add a compound to make it slip proof should the floor get wet (garage floors get wet?

)
Plus it's really concrete, so it won't get damaged or hurt by chemicals! Takes three days from application to completed product.
I visited their showroom and I am impressed with what they have to offer. I have to save up for awhile to afford that $3200 estimate though...
