For those who are interested in the same thing as in my original post, check out www.seal-it.com
and look at their Concrete Sealer, which happens to be clear.
The rest of you who felt the need to make assumptions as to the reasons why I'd like to seal the floor, you were wrong.
When one spends upward of $500k on a new home, its worth looking into a product which would help keep its appearance. Not only from an everyday standpoint, but also in cases where the eventual spills of oil, coolant, chemicals, paint, etc. are easily cleaned up instead of staining the floor or being stepped in and tracked through the house.
Im from the school where you take care of your things, be it your tools, cars, house, and they will last much longer. Im not one to look the other way just because things happen.
Why bother painting the exterior of the house if that's the thought process? Because it looks nice? I paint mine to protect it, even though I don't spend much time sitting next to it.
Peeling paint and coatings that cannot withstand the everyday uses of a garage without being "careful" are not what I'm after, hence my original post.
