looking to use D151 on my car, followed by black hole, and topped with a sealant and/or wax. Will the black hole be as effective following an all in one like D151?
I can't tell you yes or no. In my experience D151 doesn't play well with some sealants and waxes. I have never tried it with a glaze. In all honesty I wouldn't use a AIO product only to top it with a sealant or glaze since D151 has a wax formulated in already. If you want just a one step polish and then mix and add other step I would suggest PB's Pro polish or if you need to go more agressive Menz PO203 power finish.
