Re: "hydrocote" is spelled.....(?)
I have prints finished that way as old as 4 years. No cracking, no yellowing. I have not tried to fold and/or bend them excessively, though... (I mean past normal handling conditions.) It gives a hard, impermeable surface but it looks quite flexible in the same time. (I guess it should be that way, since wood is not a quite dimensionally stable material - if I'm not mistaking.)
