Poorboys black hole is predominately a hand applied product and it is just a glaze with loads of fillers, it will not remove swirls but just hide a few like super resin polish, it is just better for darker coloured paints. If you really want to get rid of the swirls the paint will need a polish there is no other way and Menz polish is the best. There is a huge difference between polish,glaze,wax, sealant etc. After a polish you will want to cleanse the paint with something like limeprime or limeprime light before applying black hole, sealant & wax.
