Yes toolow,
The DPFL is an Excellent foundation on which to spray your K-36 or NCP 271 ( both good products )

On a side note : you can scuff sand ( 150-220 grit) the DPLF after overnight dry and apply your body filler right over the top , as reccomended by PPG .
Then you can spray your K-36 over that too .
I make my body men send me their palstic work in 180 as this helps in not having to spray as many coats of primer (NCP-271) over the work , and it blocks quicker and easier . Plus most OEM paint manufacturers are now recommending finer grits on finish work !
