Wet sanding the epoxy was a drag, took a lot of elbow grease. But I got it all sanded, cleaned the garage, put plastic up and seal up around the doors. Got 4 coats of color on, the silver was slow to cover, need to clear coat tonight.
This is the first coat so it's a little blotchy, but after four coats it's pretty even. You can't tell from the picture, but it's really bright mettalic silver.
