Thank you for posting your review. We're sorry to hear about your experience with Painter's Putty '53'. Most "oil-based" putties and fillers, including DAP Painter's Putty '53' do not set with enough hardness to allow for proper sanding. As indicated on the product label and supporting documentation: "Product should be tooled and finished while wet, as product will not sand well. When used as a filler, Painter's Putty '53' requires 24 to 48 hours to "skin" (surface dry) for paint application. The product can take several more days to dry firm (not hard). For best results, prime Painter’s Putty ‘53' with an oil-based primer before painting with latex paints.” When DAP '53' is applied as directed and primed/painted with the recommended oil-based products, the oil migration that you describe does not occur. For wood repairs where sanding and fine finishing are required and/or where the use of only water based primed/paints are preferred, we would recommend the use of products like Plastic Wood All-Purpose or Plastic Wood-X Wood Filler. Should you have any additional questions, please feel free to reach out to DAP’s Technical Customer Service Department at 888-327-8477.
