Hi so I’m looking to repaint this because I messed up in more places than just here. What would be the best way to remove these layers of paint? Just sanding with higher grit sandpaper? Also what’s the strategy for good masking? Almost every time I do it I feel like everything’s covered but then I get spots like this. Lastly, how would you recommend I mask this gray band area? I tried putting tape under the little white lip there so the walls could stay white, but they were thick which prevented some of the gray from going where it needed to.
Thank you!
