Dear,
I don't know the correct answer to your question, but I can give some suggestions regarding on what you have - (you'll only know for sure what will be better after the test spot).
As said above, finishing glaze from wolfgang is a fine polish and a glaze, and it's supposed to be used prior wolfgang's sealant, so don't worry about the 'sealant over glaze' issue you were concerned. Also, like you're using Powerlock, I doubt you'll face any 'compatibility or bonding issues' with the combination above since all the products you have are supposed to work great together.
------ If using finishing glaze (from wolfgang in this case) over a sealant, odds are you'll 'harm' your sealant layer, since this product has abrasives. -------
If you're going to follow your compounding step with TSR (total swirl remover) or FG (finishing glaze) will depend on the outcome of your compounding step, and your expectations.
If you face the need of much improvement over the compounding step, I would try TSR on white pad. If not that much needed, I would try FG on white pad. If just slight improvement needed, maybe the FG on gray (I call black) finishing pad.
In some cases, even after using TSR on white pad you'll benefit from FG on black pad...
All said above, you'll only know for sure after testing a spot.
If you do your homework and use the products you have in a correct manner, you'll be blown by results at the end. You got it all!, nice choice of products to work with.
Please, let us know,
Kind Regards.
