Are you serious? The counter tops in my darkroom are high density particle board finished with two coats of standard, run of the mill, glossy urethane finish. The same thing used for finishing wood floors. This stuff is tough. Everything gets spilled on it and in the 10 years that I've had this set up, nothing has damaged it. It doesn't look like the OP is going to be running water over this thing anyway, not that it would matter.
