don't leave it on too long
Having just taken delivery of a new deep red metallic car, & not wanting to pay the dealer's charge for GardX I decided to do it myself. Firstly I applied the Gtechniq Panel Wipe with no problem, then following the video I applied the Miyabi. However, where I went wrong was I left it on the car for about an hour before rubbing off. It wouldn't rub off, just kept smearing leaving an oily film. A quick call to UF and it was apparent that I'd left it on too long. Another clean with Panel Wipe & I re applied it. A lot more sparingly this time, & I rubbed it off after 20 mins and the results are truly outstanding. After 24 hours the effect is even more dramatic. Unfortunately, there is a small patch left on the rear hatch which I missed when I re-applied the Panel Wipe after the first attempt, and this I can't remove.
