Just my input mate...
I will wash the car with two bucket method and wool washmit Sounds good to me, a pressure washer is quite important for initial rinsing to remove as much as possible before the first contact with mitt if possible
What washing product should I buy to prep new car?Dodo's Born To Be Mild all the way mate, you'll be hard pushed to find anything much better.
After washing was going to use lime prime lite to remove any wax etc. is this ok for new car?LPL will be ok when used correctly, it can be a bit tricky on older paint types but you should be fine on your new stuff, just keep it to small working areas and DO NOT let it dry, wipe on wipe off.
Was then going use poorboys xp to seal the paint. Ok for new car?Can't comment as I've never used it, should be ok
Was then going to use supernatural as a final waxPERFECT! really fantastic results on solid colours
Will then clean and seal glass and apply a product to dash etc.Can highly recommend SN glass sealant but shouldn't be any need to cover a new dash in anything
Can I seal panoramic glass roof with sealant and wax ?You can but I'd opt for a glass sealant myself
Was going to use a Product to seal the wheels not sure which one though?SN hybrid would be my first choice for wheels, a doddle to use and lasts ages too
Hope thats been of some use
