Yesterday I polished my silver clio 197 with autoglym extra deep gloss polish and ill never use it again, it didn't go on very nice and wouldn't come off without massive amounts of effort and when it eventually did decide to part company with my paintwork it left it looking nothing more than just clean,, so today I had the bright idea to use autoglym extra gloss protection on my black impreza and to be fair it went on very nice, but just wouldn't come off, even worse than the extra deep gloss polish and what did come off like the dung I'd used on the clio left a dissapointing shine in the end I resorted to using autosmart "wax" to get the other sh*te off and the difference in the finish between the autoglym and autosmart products was like day and night, i'll never use that cr*p again.
