Ive washed it 2 times already, it hold on like paint. Its just slightly rubbery. There are people that have this shit on for years i guess. It has everything to do with the surface and how many coats you do.
here is a shot outside. I went ahead and did an extra 3 coats today because i like it and i want it to last. total was 9 coats.
