Re: Cleaning products - How much would you spend?
I spent £70 on a tub of Swissvax Saphir wax. Wouldn't go above that, even though it's got the "Mystery Wax" on it at present which costs £300 per tub (thanks to the very nice Roy from The Shine Experience). I have invested a lot in my car and plan to keep it for a while, so I want to keep it looking good. I've found if you have a really good quality finish it's actually easier to keep clean. It took about 25 minutes to wash and dry the whole thing last night (excluding wheels which are a bit of a pain due to the brake dust - see other thread!). The dead insects came off easily, the water just fell off the excellent wax finish.
I use a mix of other products that are definitely at the premium end of the market. But I find they actually last quite well and do give a good quality finish.
