From what i've read, your best bet might be to rent a shot blaster or floor surfacer to remove the old paint. Local rental places here were no help but you might have better luck. As mentioned, Garage Journal site has lots of info on this subject. I'd check there for other opinions. I just know that if you don't get the existing surface coating off there will be problems .
