I recently finished painting my boat with Glidden's Poly Floor and Porch paint and it's been about 4 or 5 days and it is scratching really easily. I had a guy spray it and he had to thin it so I'm wondering if that had anything to do with it? Is there anything I can do to protect it (besides re-painting or being really careful)? Maybe a sealer or top coat or something I don't know... Thanks...
