I'm running out of 16 oz. (1/2 liter) paper cups I use with lacquer, mixing, holding the strainer, etc. The local stores don't seem to carry paper cups any larger than 5 oz. Dixie cups. I tried one type of plastic cup and the cup color begin melting seeping into the lacquer, as I thought it might.
I use clear plastic cocktail cups that I buy from the local grocery store. They are only six ounces, but if you can find the same clear ones in what I call "roadie" cup size, you won't have the color melt problem.
I use regular coffee cups I get at my local Tim Hortons (little plug there lol) They work fine for me, I also work at a cabinet shop and thats what the guys in the spray booth use as well. You should be able to buy a sleeve from your local coffee shop or just wash out some after your coffee is all gone.
Cut the top off a cardboard quart milk carton, or any plastic bottle that is made of polyethelyne, the milky looking plastic. Poly is immune to all solvents as far as I know. That's why nobody has ever come up with a glue for polyethelyne.
Might try a local restaurant supply house. They may carry an appropriate size paper cup.
If you must go to a plastic cup, try the local convenience store. I won't make any guarantees about the plastic, so you'll have to experiment. The convenience store I most frequent (Quick Trip) has a number of different sizes and they have ounce graduation markings on the side of the cups. They seem to hold up well enough for what I use. They also have convenient snap-on lids that keeps stuff out of my mixtures.
At a local store I asked for plastic cups made with polyethelyne. No one even knew what polyethelyne was. So I bought cups marked with the recycle number "1", and were marked with "PETE". Lacquer thinner did not melt these cups. Yea, success.
Now I wonder why the manufacturer named the cups, Pete. I think Bob is a better name.
