I get a little overwhelmed when I try and digest all the information on this forum. I understand SPI is intended for bare metal. I understand wiping down bare metal with SPI solvent base followed by SPI water born. What I am not sure of is after epoxy has been applied and before filler is applied, should the surface be cleaned with both or either solvent base and water born? After filler has been applied and blocked, should both or either solvent and water born be used before applying 2K Primer? Same question for prep step between 2K and Epoxy sealer, and again for sealer to base?
