Continuity mistake: After the girls have seen the site of their next job, Rosemary hands Laura the keys to the Rover. Laura has a bag over her right shoulder. When she climbs into the Rover and closes the door, the shoulder strap of her bag vanishes.
Continuity mistake: Near the end, Laura is pouring the champagne, but while she's pouring it, Lydia and Penelope have their glasses filled to the top in front of them, but Laura hadn't finished pouring it yet.
Chosen answer: As far as hanging new wallpaper, there is no need to brush on any additional product once it has been pasted to the wall. It appears Helena may be doing an extra decorative step by applying a liquid glaze over the wallpaper to give it a more distinctive look, perhaps creating a sheen effect on the surface. Glaze can also be tinted to give a muted colored tone. It could also be a protective sealant. However, to remove old wallpaper, a product is brushed on that dissolves the old paste so the paper can be easily scraped off.
