Don, yes PPG still reccomends doing it the way you have described, but with all the new products they have developed , I havent used the DP line in at least 4 years .
DPLF isnt the best product to use in a production shop as it has a tendency to soak up a paint job
( loose its shine), when you put the heat to it in a bake booth. Its still a good professional product but beings they had to redesign the product( remove lead content) its not as good as it once was IMO.

I used it( DPLF 90) on my 37 after having it sand blasted as you cant beat it if its going to sit for awhile before doing any body work to it .
