I’ve been using Kovalent products for more than a few years and it seems to never disappoint me. Maintaining boats, ships and vessels is a tideuos tasks but Kovalent has made this job certainly easy with their high performance products for every need you could possibly have. I have never had the urge to switch since the quality I received has been extraordinary time and again with a very formidable after sales process. I seemed to be looked after at all stages. Good on ya Kovalent .. keep the good work up!
