Recently got some 2k urethane primer / sealer with hardner, didnt have any reducer included in the kit. It calls for exempt reducer non photochemically reactive. Cant seem to find the non photochemically reactive or it doesnt say on the cans. Would regular urethane reducer that says photchemically reactive or unmarked work??? dont understand why it would have to be non photochemically reactive since it is a high build primer that will be covered by topcoats. Someone please explain the differences to me and advise greatly appreciated. There are some places on the current panels with a lacquer based primer on it, will there be a reaction problem or anything else with these. BTW the topcoat will be urethane enamel.
