New guy here 
I have a 3 car garage in SW Florida that I want to resurface. Currently it has a builders standard epoxy finish that has stood up very well over the last 5 years with only one small spot (about 3 inches in diameter) that has pulled up.
If I recoat with a higher quality epoxy, I assume I should diamond grind what is there now to insure a good bond. Maybe I could get away with rough sanding only since the epoxy on there seems to be well bonded to the concrete, I’m not sure.
What I really like is the Racedeck but I’m very concerned with water settling underneath and creating mold or other breeding ground.
Also, I would be putting a in lift. I haven’t decided between a 4 post and a mid rise scissor. I don’t know how well the Racedeck will hold up for that.
The epoxy is less expensive, more labor intensive to install and easy to maintain. The Race deck is far better looking but more expensive and the unknown moisture issue.
Any experience or advice is appreciated.
