so guy, which polish then? SRP is the one of choice for me, just cos i aint got that much time and a quick cover up is needed most fo the time for the missus's car. Got some swirls that need to "go" though.
SRP is ok for what you say you use it for... it is just that a lot of people advocate for everything!

'my interior needs cleaning' - use some SRP mate
'my black trim is faded' - use some SRP mate
'my botty is dirty' - use some SRP mate!
i digress, if i am polishing by hand I prefer dodo lime prime, easy on/off and works a treat.. seems to last forever too... LP also doesn't contain oils so is a perfect base for waxes & sealants of your choice
this thread contains pichers of lime prime applied via a rotary with some great results.. the swirls have been removed and not just filled
