Are these coatings brittle? LT's f**k with ground clearance as it is . If you hit a rock or a speed bump will this chip or break the coating? Also can an average guy install them by himself With jack stands and no helping hands ? I use to be a pretty wrench but that was along time ago! But I would still like to do it myself! If it is too hard for one person how about mids instead of LT's if they still make them? thanks.
