When I painted my Carlton, I thought that the top of the washing machine would be a good place to mix the paint because it was the cleanest spot in the garage and any spills would be easy to clean off of the porcelain. I stupidly used a styrofoam cup and it melted as soon as I added the reducer and hardener to the paint. The paint went down inside the washer which was full of clothes. Luckily, I only ruined one pair of jeans and I was able to clean up the mess before my wife saw it.
