Note: For contractors using our 40lb. boxless Direct Fire Gray (Item #2082) joint sealant please note we do not recommend reheating the product more than twice, as it breakdowns after that. The gray Direct Fire will work great in an oil jacketed heater, but please make sure the unit is clean as possible prior to using as black residue will affect color of the product.
