Last summer I put a floor polish from Walmart on my Catalina 27 interior bulkheads that was recommended in the forum. The bulkheads are made from the typical plastic laminate of most stock production sailboats of the 70's and 80's. I wanted something that would last a while. Most of it looks good, but a few spots are cloudy from over application, I guess. Any ideas on how to get it off? I have tried most everything...I even tried scraping it off with a razor blade. No luck yet. Of course I don't want to damage the bulkhead. Any help would be most appreciated. Thanks.
