After being laid low by the plague, felt well enough to spend an hour in the garage.
Applied a first coat of the lacquer. Small amount of stain lifted, but all ok. It's weird stuff, slow moving, like treacle. Applied with a paper towel, which was an option and fine.
Body just sucked it up; going to give it 20 minutes and apply a second coat with a brush, then leave it for a couple of days.
