So logic would indicate that it has survived this long, either it's probably been sealed at some point or doesn't need it. How to tell though? I sure don't want to mess it up and I am guessing I will need to try a handful of different rubbers before settling one I like. I will probably be trying out both OX and sponge. I use the Tibhar glue sheets from Paddle Palace if it matters.

Oops, I did not mean to post this in Long Pimple rubbers, but not sure how to move it

The old (VOC) glues were much less harmful to wood compared to the current water-based glues. So I would still seal it if you can, to provide some protection again water-based glues.
Glue sheets can also be very hard to remove sometimes, so an extra seal to protect fibres from coming off is worth it IMO.

PS Topic moved to the blade section.

Good points thank you! And thank you for moving it to the proper place

Being a 3- ply blade,I suggest sealing it.Besides, If you are a blocker all the better since this kind of 3-ply blades get stiffer and benefit the blocking style.A bit more sealing liquid,adds extra stiffness.
