I have used brightsides and the two-part polyurethanes and I assure you that the best is the two part. Brightsides is soft. It will chip off with a fingernail and does not really offer a tough shield. I purchased a two-part that could be rolled on but I finally went with a sprayed on finish . It looks fine and the finish is so much harder than the Brightsides that the trouble and expense was worth it. Brian
