Just a quick reply.
Epoxy painting of concrete surfaces depends entirely on the prep.
I've been involved in many hanger finish/refinishing.
Brand new concrete is the best to paint. No oil or grease etc.
This leads to an extremely durable finish and its very resistant to gas and Oil.
Older concrete is more problematic.
Old painted floors are even worse.
On the older concrete the painting is the easy part...it absolutely has to be clean and prep'ed.
Often prolonged exposure to gas will cook the epoxy off the floor.
Seems to be a particular problem with Modern car gas. Av-gas (100LL doesn't make it peel.
I used Bahr on my house garage. Prolonged gas from say a carb overflow would peel the epoxy. I usually sanded the spot and repainted it.
On the new house I went with the snap together tile.
I have had a problem with prolonged exposure to car gas discoloring the White squares. Leaves a yellow stain on them.
I snap them out and bleach them with some plain old clorine bleach.
Doesn't do anything to the Black ones.
Overall I'm happier with the Tile. As others have said....its a hell of alot less slippery then painted surface.
An additional benefit...if you move you can take the tile with ya

On a side note....if your building a shop or garage...the best thing I have seen it 20 years is PIGMENTED POILISHED CONCRETE.
Concrete has a pigment mixed in when its poured. After setting its polished.
When the floor dulls....give it a sand and polish. Voila...fresh concrete and a high gloss finish.
We have one hanger on the airport built in the 50's to fit a DC-3. I can tell you the floor is still pistine and looking great.
