Denny,

Since you are priming the bare metal with PPG DP90, (step 1), according to the DP90 spec sheet: https://buyat.ppg.com/refinishProdu...eID=00d4601a-2f0c-4728-adff-94c7c5b64ea5

DP90 can be top coated with DF body filler. So applying DF filler would be your step 2.

Once you have the filler to where you want it, then according to the PPG K36 spec sheet:
https://buyat.ppg.com/refinishProdu...eID=2896826e-e503-4c01-8471-58c8763921aa

K36 can be applied directly over the DF body filler and the DP90. This would be your step 3.

Not sure if this is opinion 89 or not, but I figure if PPG says this is the way to go, (and I'm certainly not saying the other 88 are wrong), I would tend to lean this way.....

BTW, DF filler is not listed as an approved topcoat for K36. Nor is any other filler it appears.
