The tool you're using just doesn't have the guts to get the results you're after. Once the 7424 comes in you'll see exactly what I mean. It also sounds like you may been almost dry buffing a couple of products or just working them too long - either way, all Meguiar's paint cleaners and polishes should be wiped off while still wet and never allowed to dry. Waxes and sealants should allow to haze over before removal.
