Is this varnish aquarium safe?

I have been told that I can coat fake bamboo stalks with a clear polyurethane varnish (to keep the rubbery stalks from pealing once submerged in the water), then place the stalks in my aquarium (after allowing the stalks to dry for 24 hours) without it harming my fish, and I am wondering, this is in fact correct?

Also, while a clear polyurethane was suggested, I am wondering if my Minwax Polycrylic Protective Finish (satin) can be used instead? If not, I can run out tomorrow at pick up some Minwax Polyurethane.

I just want to make sure that whatever I use it doesn't harm my fish.
 
I've read that polyurethane varnish is safe. You're supposed to use a few coats, and make sure each coat is dry before applying another one.

Don't know about those products specifically, but if it were me, I'd wait much longer than 24 hours, and I'd put them in non-tank water first, just in case any toxins remain.

HTH,

Alright. I plan to pick up some Polyurethane, instead of using the Polycrylic Protective Finish since I am not certain if it can be used in place of regular ole' Polyurethane varnish.

After I allow the stalks dry for 24 hours, would you recommend that I then let them sit in non-tank water for another 24 hours before placing them in the actual aquarium?
 
I don't know about this one.... my kitchen table is finished with clear polyurethane (several coats, I finished it myself) My cat knocked over a glass of water that went un noticed for a couple of hours. Where the water was the finish turned a white milky color. It's definitely not meant to be continuously wet, much les submerged. I wouldn't try this in my tank. At least do a test piece in some plain water before trying this in your tank!
 
Use a marine resin/polyurethane. It's waterproof and won't leach chems into your water. Look at pool supply stores or on the 'Net.
