Naw , don ' t need gallons of paint thinner . What i ' d do is get a broom and a brush and get the bodies off as much as possible , wipe it down with maybe some water to get as much as as you can off and then get some acetone or Lacquer thinner on a rag and gently wipe the rest off . You might have to slap another quick coat on cover marks but that thinner should melt the moth ' s paint marks smooth as long as you don ' t rub too hard and rub the paint off . <| sep |> If you want to familiarize a nongaming partner with first person control I always recommend Portal 2 coop . It starts rather easy and gets more difficult as time goes on . It has a pointing mechanic that makes it easier to point things out and it ' s quite humorous without a penalty for dying .
