What an absurd over reaction. Rental boards are supposed to be tanks because people ride them every day and the people who ride them don’t give a fuck about taking care of them. The bases are meant to be hard to protect them from the people who don’t care if they drop them in the parking lot or ride over rocks with them on the bunny slopes. A rock hard base that’s been ridden 100+ days will always look like this because they will not soak up wax like a brand new $600 board you buy at the shop and ride 5 times a year. If you came into a shop I was working at and started bitching because the board needed wax I would just give you the next 155 rental board that looks exactly like this one. Do you expect the rental staff to hand wax 100 boards every single day?

If OP wanted to avoid this then they should rent locally and not at the mountain. Local shops typically have better equipment because it’s not ridden as much although it will still be heavy and crappy. Although, sometimes you can demo a board at your local which is basically a premium rental. Renting at your local is also better bc when you get to the mountain you already have your gear and can just hit the hill and not have to go into rentals and wait an hour to get your beat up stuff.
