Plating Tank - Zinc

[aermakov@rogers.com]

Hi.
Just wanted to know if I can use Rubbermaid plastic storage container for Copy Cad plating solution. The shape of the container and capacity are more suitable for me, compared to a default round bucket, and they also sell a lid for these.
Is there a way to test these containers for suitability? I don't want to contaminate my plating solution or have it "eat" through the plastic 6 months from now. Just a note, Rubbermaid doesn't say what the container is made of.
Also, I need to buy additional 4 gal. of zinc plating concentrate from you, I assume that it is OK to mix old and newly mixed solutions together? I already have 23 liters of the stuff. Thanks.
Andrew.

Yes, you can use Rubbermaid containers. Make sure they're waterproof
