Hello, I just bought a Fuji mini mite 4 with gxpc gun. I need to spray an interior door. I also am building a Murphy bed and office desk cabinets. I would like to use the same product on everything. The color will be white. I would really like to use a product that will work well with the factory tip in the gxpc (but not a complete deal breaker if not possible). I was reading really good things about PPG Break Through. Would that be a product that would work well for me and my setup? I read that I wouldn't need to prime if using the PPG? Can anyone confirm that? What about thinning? Thank you for any help you can offer.
