The best thing that you can do to protect your vehicle is to prevent the damage in the first place. If the bug acid has already done some damage, you will HAVE to paint; there’s simply no way around it. Don’t waste your money on paint repair kits. They will help, but they will not give perfect results. As a matter of fact, paint repair kits—like touch-up paints—won’t come anywhere close to looking good. It’s better to protect your paint than repair it.
