Thank you for posting your feedback. We are sorry to see your low star review on DAP Drydex Spackling Paste. Paint "flashing" can occur where insufficient paint film thickness has been applied. This issue as described, is almost always able to be corrected with the application of a second coat of paint. Should you have any additional questions, require further assistance, or wish to discuss this in more detail, please contact DAP’s Technical Customer Service Department at 888-327-8477.
