Tough stains
Too often folks have not cleaned the rub rail. There are all types of solutions; however if everything else fails, then the last resort is the following. Use acetone as the last resort. IF that don't get it, then you can sand the sucker with maybe 400 grit wet and dry.If using acetone on the HCT boats or anything under the 212, be extremely careful not to get acetone on your boat or it will melt.Crazy Dave Condon
