We have had it for a few months and of course I had to test it first!! Yes it is very good, I dont think it takes paint off, AG do a version of TCut called Paint Renovator for taking paint off.
I heard about this product well before launch. I will contact Autoglym Customer Services next week and find out what is going on. A bit of polish is not a bad thing, but it depends how much. As this product is probably aimed at U.K. market we often mix the term Polish, Car Wax etc and the average punter does not distinguish between them, so it could just be marketing hype. But worth checking out.
