As I have been sanding the interior of the cab of my 1957 pickup, I have been using Duplicolor sandable and filler primer as I go, to guard against flash rust. I will be using Omni/PPG MP180 2K sealer before painting. The sealer can be applied over a lacquer primer, but I am not sure if the Duplicolor primers are lacquer or enamel. I know both contain ketones and the sandable primer also contains toluene. Does anyone know if they are OK to apply the sealer over, or do I need to sand the Duplicolor primers off first. Thanks.
