Has anyone used showroom shine or similar water free cleaning products? I am interested on opinions. I am a bit sceptical and worry the paint will be damaged?

Thoughts please

Yes I've been using showroom shine for a couple of years, and it's great. I was put onto it by a mate of mine who has a couple of lovely old BMWs and is very particular about his paintwork, and neither of us has had any problems.

No swirls/micro scratches?

Personally, as Ive said before in several similar threads, I wouldnt use it

Give the car a quick wash first to remove worst dirt. This stuff gives a fantastic polish without any hard effort.

If you use it like that..possibly safer

But there are good sealers, waxes and QD's out there that can/will do a better job
