i normally just wrap some 4inch scrim round the angle first then normal skim bead ontop of that then scrim down the wings ive been doin this for years without any cracks
For **** sake take it out it takes two minutes rarely makes a mess and they come out in one if you prise them out bit of bonding to bed your skim bead on guaranteeeeeeeeeeeeeed it aint gonna crack. Wood moves all year round so if it dont crack after a few weeks it can still crack in the future.
