Nothing wrong with the product itself however, this is the second time in a row that I receive this kit with damage to the containers that occurs during shipping. I have informed customer service about shipping damage and it is still happening. I wish the packing department would consider how irresponsible shipping companies are with packages.

Q: Are the technical data sheets available for the Jeffco Epoxy Laminating System?

Yes, we have added the Tech Data Sheets to this web page under the "Documents" tab.

Q: What is the shelf life after the resin and the hardener are opened?

Per the supplier: As long as the lid stays on it and it is nice and tight, it should last about 1 year.

Q: Exactly how much resin and how much hardener is in the 5 gallon kit (01-07925)? Is 5 gallons the total of resin plus hardener? Or is it 5 gallons of resin plus 1.25 gallons of hardener (total of 6.25 gallons)?

This has 5 one gallon cans of resin and 1 gallon can & one quart can of hardener. When mixed, it should yield approx. 6.25 gallons of laminating material.
