We are in the middle of restoring a Farmall Regular and are using PPG Epoxy primer and reducer. Have never sprayed this before and wanted to know a few things. First, I was informed that it needs painted after 5 hours, but should be painted immediately or else it needs scotch brited completely. Can it be wet sanded in the mean time to provide a smoother surface? Also, what ratio of reducer to primer do you recommend for the best job? And lastly, what air pressure should the gun be operated at to shoot this type of primer? Any advice would be appreciated. Thanks!
