paint questiion again!!!

[Dom]

I need to varnish the whole INSIDE of my cage (its got a plywood interior wich needs to be covered..)

I am not looking for something fancy .. but simply something that willl make it reasonably waterproof during heavy misting and lessen the offgasing of the plywood..

I was looking into using a verathane water based...

Is this a good idea? If so .. how long before I can put my cute non-furry creatures back in..

Any other sugg. would be apreciated!

Thanks in advance Dom
