Hi, I'm planning to make window sills out of MDF and I'm considering trying to transition to the drywall without any trim, i.e., trying to create an invisible joint at the corner between the window sill and the drywall. Does anyone have tips on suitable sealant/putty for this? Can/should you use corner protectors? I've heard somewhere that it doesn't work well to putty a joint between MDF and drywall, but I thought I'd ask if anyone has any tips!
