I have had several tins of Protek totally evaporate, in my shop, but it is Arizona and my shop sometimes gets to 90 to 100 degrees. I checked the cans, and each would not seal well. That is, put the cap on tightly, then squeeze, and listen to the air going in and out. Try it. They are lousy containers. More to the point, the material should be able to be resuspended in some solvent. I have saved the cans with the material caked at the bottom. Have not had time to try experimentation yet, but has anyone else tried and found a good solvent to reconstitute the materials? Bill Simon Phoenix
