I applied an epoxy base coat, then an epoxy color coat using Magic resin products. These steps went well. I then applied a poly finish coat and it set up faster than expected. Mixing and pot time was less than 5 minutes. My working time was at 15 minutes from pour when I wasn't able to work it anymore. Applying two gallons total. First time user. Ended up with lots of ridges, ripples, uneven rough finish.
The poly appears to be durable, just didn't end up with the finish I wanting.
I'm going to wait a few years to see how it holds up. If good, I'll sand and try again. Maybe one gallon at a time.
