HELP we have a 48 foot race car trailer that has graffiti allover it.............? - aluminum car trailer

But the trouble is that we are racing this weekend and graffiti actually pretty bad. The trailer aluminum parts are black and they are very flexible, we do not have time to paint. Who knows, solvents, they know that they can work, we have a lot. I am open to all suggestions seriously! Please help! Note that you can not damage the color of choice because we do not want to paint. I need to know by Friday evening! THANK YOU!
