I’ve heard some people use fingernail polish, depending on the size of the chip. If that’s a possibility, I recommend going to your local dollar store. Then if necessary, you can get a few colors and mix it just right. That Viper Red is so pretty!Hi folks. i have a Trek Super Commuter +8 e-bike and it's the Viper Red color. I was wondering where i can buy matching touch up paint for this specific red color? Thanks much for direction.
