Hi there. I have asked this question on the gel coat site but need many different thoughts on the subject so I thought I would post here as well. I almost lost a wheel ( have you packed your bearing this year) on the trailer this week ( another story) but everything was saved with what could have been a big problem being a little problem. But now I have a residual problem the wheel bearing when it gave way splashed bearing grease on the hull. I have cleaned it off but still have a grease stain. What do you think would take this off . It is about 3 inches around where it spite the grease out of the hub. Thanks for your input.
