I'm with you there mate!! My aunty had a solid black MX5 and bought 'today's special value' from QVC

which was a Mer package with wash, polish, window stuff etc etc. I said that i'd wash and wax it for her and tried her Mer products. They really are terrible!!! Likewise, reading through the instructions i couldn't help but laugh. I also applied the polish to a wet car with a wet polishing cloth and yep, i couldn't get it off!! I wouldn't ever go near the stuff even if it really was the last thing on earth!
