Waterproof Printer Paper

I mentioned the other day that I had an idea for a new Crop Lifetime log format.While I haven't spent time on the format yet, I did order some water proof printer paper which apparently you can write on with a regular pen.  Well, they'd like you do buy a special pen but some quick research suggests that a regular permanent pen will work fine.

Once I design the worksheet I will print a couple copies on this paper and then put them in a binder.  I may also get them spiral bound at Staples or something.
