It depends what you are doing Josh. Look at my "last picture". My door had chipped paint and I needed to build and feather the corner of the cowl. I normally would have used a 2k primer there but for an area that size I just put an extra couple of coats of SPI epoxy over about an 5 hour period, gave it 4 days and blocked it out. One step and it is ready to paint. Cost is not an issue since I only used 150 ML of sprayable product. I do not think I would have done that with DPLF. For one thing, it does not have the build qualities and second it is pretty gummy to block sand until it sits a long time. JMHO
No one, me or anyone else would suggest that Epoxy primer replaces good 2k high build primer.
