what sorta basic shopping list would i need mate
Depends on what you have!
I presume you already know how to wash a car with 2BM and clay it. I also assume you have a glazing agent/sealant/wax.
I'd go polisher + pads + polishes - you can buy these in various packs/deals so you don't have to hunt around.
3M blue tape and lots of it. Maybe two rolls. You need to tape off bits like rubber trim etc.
Extension cord for polisher.
Some quick detailer spray - to moisten the pad so the polish doesn't dry out.
Optional:
- smaller backing plate and pads for those trickier/smaller areas like boot lip.
- IPA so you can mix it with water and wipe down the paintwork to remove polish residue.
Can't think of anything else at the moment.
