Thanks for the compliments. I only wish I had a new clean slate like you! It must be exciting to start fresh.
I used a commercial grade two part epoxy. I had it installed professionally. The two sides of the garage were done about 5 years apart, hence the color difference. (The left side was a new addition. The right side is the original carriage house)
It's holding up very well. One side is probably 10 years old now and has been through everything you can imagine. Car restorations, chemicals, salt, etc.
Before I had this I tried the Griots system and another do-it-yourself system. I followed all instructions (I'm pretty handy and quite anal with the details) however neither one lasted. It came up under the tires, chipped too easy, etc.
I found a commercial installer and made a deal with them to do my garage "on the side" when they had time. (They normally did huge factories, etc.) It was worth it.
