I just use the standard squirt bottle for mine but for a large area or complete it would be great. I actually have one I got at HF for keeping the shower/bathtub cleaner in. I have to do the tub cause my wife can't take the fumes and it's SO much quicker. Not sure about the lacquer thinner with the HF one. Not really sure "why" you would be spraying that much lac thinner either.
I'm sure Milo has a reason though.
