It is better if the floor is dead clean before you put on the epoxy.
The kit (I've used 2 of them on a double garage) has an acid etchant.
Says concrete should be at least a couple of months old, etc.

There are drip pan you can slide under a car to catch oil drips. Maybe
$10 in any good auto parts store. I have a Jeep Cherokee that oozes oil
and grease...

The tire problem is of concern... I have removed the epoxy in a couple
of spots with tire turning. I suspect I might not have gotten the epoxy
on thick enough. You should roll a genereous coat, IMHO.

If you're realy serious about painting the floor & wanting it to last

I would use Rustoleum Industrial DTM Epoxy Mastic (9100 System) 2
coats

here's the tech info on prep & application

I've been using this product on shop, lab & garage floors for 20+
years
years.

I have been extemely satisfied.

The last garage floor I painted was 5 years old when I prepped &
painted it.

It had some oil spots & some small (larger than harline) cracks. The
stuff's been down for 6 years. Mountain environment, snow, sometimes
tire chains, road ashes. Some cars w/ small oil leaks.

No summer peel off (yet)

So far so good (again) looks like I'll get at least another 10 years
before
I'll need to recoat (not sure it will be needed but to maintain coating
integrity). With the
second go 'round, the stuff will probably outlast me.

cheers
