Being a high school woodshop teacher I'm always trying to find easier ways for students to finish their own projects. Spraying for the students is not allowed at our school because of insurance reasons. We've started using General Finishes arm-r-seal and seal-a-cell and found it very easy to use and comes out great. The questions I have is storage. Being that is has a short shelf life after opened I've thought about putting the remaining amounts in the can into a clean, dry water bottle with a screw on lid. This way I could squeeze the air out and then tighten the lid. Does this sound like it would work or am I missing something?
