Unless you’re planning to machine polish then I would omit the clay mitt stage and include a tar removal stage using Autosmart Tardis or something similar. Claying will cause marring that you wouldn’t be able to fix by hand, you will just mask it using the SRP.
If you want the best life out of the DSW I would also omit the SRP stage and add in a panel wipe stage before applying DSW. However, if you’re happy with the longevity with DSW over SRP then leave it as it is.
Other than that it seems pretty good to me, my routine is as follows.
Clean wheels
Snow foam
Rinse
Shampoo car
Rinse & dry
Tar remover on car and alloys
Rinse
Fallout remover on car and alloys
Rinse
Shampoo car
Rinse and dry
Panel wipe
Apply wax/sealant to car
Apply wheel sealant
If I decide to machine polish then I would clay after the fallout remover and machine polish before the final panel wipe ready for applying my wax or sealant of choice.
This whole routine usually only gets done 1-2 times a year.
