PhotoThe Thompsons Company of Cleveland, Ohio, is recalling about 850,000 cans of Thompsons WaterSeal Waterproofing Wood Protector and Masonry Protector.

The contents of the cans can react with the package, causing rust to form along the can seam, which could spread to other areas of the can and create pinhole leaks.

The firm has received approximately 18 reports of leaking cans from retailers. No injuries, fires or property damage were reported.

The aerosol cans are 11 ounces and have a green or blue cap. Thompsons WaterSeal, Wood Protector or Masonry Protector, the item number and UPC code are printed on the can.
