CAHelpdesk was very helpful Helpdesk was very helpful. I think it's best to install MyChevrolet first then activate OnStar. I did the opposite, I had to sign out then log back in.

GBSeemed to Work Perfectly I was quoted $1800 by two different waterproofing companies to fix a hairline crack in a concrete foundation wall. After a little research and a phone call to RadonSeal's Technical support, I chose RadonSeal Polyurethane foam. The process was just as easy as their YouTube videos indicated. I bought a 10 ft. kit for a 9 ft. crack and it took the entire 2 tubes with the polyurethane oozing out the top of the wall. Although I have not yet had a rain to determine if it was 100% effective, I feel confident that all will be well.
