Hi, I'm wondering if anyone has ever heard of a 2k product that can be used as touch-up. Basically, I'm looking to do some quick touch-up around some holes I drilled in sheet metal (inner fenders). The color doesn't matter as the holes aren't visible, and the paint would just be for rust protection. I just want something more durable than model paint or nail polish. I am aware of the 2K aerosol paints they have now, but I was looking for something brushable.

Thanks,
Bryan

Most any 2k epoxy can be brushed on. Even where the finish matters the brushed on epoxy can be coated with 2k build primer and block sanded straight.
Be sure to wear a respirator when working with this stuff.
