Hi and welcome Ken. I haven't tried your attachment as I'm wary of them, particularly when on a work PC. I've got paint bubbling on the front lip of the hood on my 2013 and some other blemishes. I've scaled back detailing now as I'm not going to spend tons of money out of pocket to try to correct the issues. Too bad as it was a decent looking car for the first few years. Wishing you the best with your ST.
