Hey, just looking for some advice as I can't pinpoint what the issue is.
I've painted our front door, which was black beforehand. I sanded the surface before priming and even lightly sanded between all coats, but in the last day patches have been slowly developing, and getting worse as time goes on.
I used Zinsser Bullseye for the primer undercoat and Dulux Weathershield for the topcoat. The only thing I can think of is that the quality of the Dulux paint is just bad as it was OTC and not trade.
Any advice appreciated! 🙏
