I have a copper 2011 Suzuki SX4 Crossover. I bought it in May, and it is already scratched, in one spot all the way through to the metal. I'd like to get some kind of touch-up or clear coat on it to prevent rust, but I'm at a loss to find a good product. Can anyone recommend something that's easy to apply? I'm useless when it comes to auto repair, so preferably I would like to fine that can be easily brushed on and dries in a few minutes. Thanks.
