Constructive Playthings Gallon Tempera Paint, Drip-Free, Ready to Pour Black Paint with Rich, Creamy Consistency, Classroom Art Supplies, Washable, Allergen-Free, All Ages, Black, 1 Ct.

I used this to temporarily paint an old camper for an event. I mixed it in a big tub with other colors to get the shades I wanted. Then we added water for the right consistency and put it into spray guns and covered the be whole camper.One coat got good coverage, the pigment is suitably opaque. About a week later we washed it off with dish soap and a soft brush. It came off of the smooth metal surfaces no problem but it was harder to get it out of cracks. Since it was an old camper there were areas of sun-damaged plastic that held on to the paint and it probably won't come out.

I wasn't able to open the paint because of the smashed in top.
