    Default How to get rid of scuff marks on boat hull

    As shown in the photo, I've got some scuff marks from docking. How do I get rid of these? Thanks much.

    This may depend upon if these are on top of your black gelcoat, or gouged into the gelcoat.

    Not sure, but I suspect gouged into.

    Then it will depend upon how fussy you are about your boat.

    Many here will tell you to get a gelcoat repair kit and fill the gouges. You will have to do some finish sanding and polishing to make the repair seamless. Be prepared for a fair amount on elbow grease....

    If this were mine, I would do what I did for the black hull of my PWC. I went to Pep Boys and picked up a bottle of Turtle Wax black colored liquid car polish. Put it on...towel rubbed it when it dried...and my scratches were all but disappeared.

    Happy boating!

    If it's on top, acetone. If its inside, black magic marker.

    This is probably a really stupid question, but, being well known for those, I'm going to ask anyway. How can I tell whether it's just on top of the gelcoat or gouged into it?

    a gouge is very evident when the fiberglass layer is seen through the scratch, I have several on mine from incidents docking when I first started. Yours look more like surface scratches. Joe

    Looks like vinyl residue to me, I use Goof Off or mineral spirits and rewax.

    I agree with you, Joe.

    What I can tell from the picture is just cosmetic...not anything to worry about, except his pride (and joy)!

    Happy boating!

    +1 on using acetone for surface marks - works great.

    Will acetone hurt the gelcoat? Seems like a pretty strong solvent.

    I've removed quite a few scuff marks and scratches by simply using a good polish.
    Deeper ones I have got rid of by lightly using a rubbing compound and then polish.

    Difficult to tell but yours don't look too deep.

    Good luck and use them fenders next time!

    I use the purple stuff cleaner to get scuffs off.

    Acetone will disolve a corvet. Just saying,

    Acetone won't hurt gelcoat. Not sure about a corvet? If that's corvette - they are painted fiberglass, and I would expect the acetone could do bad things to the paint. But it's a different animal from gelcoat.
