The Hurculiner is much more durable than the Dupli Color. The Dupli Color is like black paint and fades quickly. The Hurculiner is rough, and fairly rugged, but dosn't last as it has no UV protection form the sun, it too fades out after a year or less. I use SEM brand spray on liner. It has an activator / hardender so it holds up to the sun. It is skid resistant even when wet. I sprayed the floor of my shower with it and it has held up excelent. You need a compresor and a rocker shutz gun to apply it but is far superior to the cheaper stuff. Its approx. 160 to 175 for the kit. Has a gallon of liner, a quart of activator, mixing bucket etc.
