How to remove scuffs on the hull

[Adetheheat]

I've got large scratches on the bow starboard from coming alongside pontoons too hard. How do I 'paint' or repair them? It's a Beneteau Antares 750 powerboat

East Coast Fibreglass have some good tutorial videos and will supply any products needed at a reasonable price ( no connection, just a customer)

You may be able to minimise the size of the scuff with wet and dry sand paper. However if the scuff is too deep. I would suggest a matching colour 2 pack polyurethane paint. It could be uised to build up the scratch and then sanded back hopefully to disguise the damage. However it is unlikelly you will be able to make repair invisible. So ultimately paint the hull. Which really means just put up with disfigurement until you add more scratches. ol'will

That's what I do but mine is an old lady so fairly scruffy to start with.. very fine wet and dry..

Adetheheat do you know if the gel coat was brushed or sprayed? If your boat was built since the mid 1990's then it will probably be sprayed. This means the gel coat is only 0.5 to 0.75mm thick. Whatever you do depends on how close to an invisible repair you want. If you never want to see any marks, then employ a glassfibre repairer, but this will cost a small fortune. You could use Teroson Gel Coat Repair to do the job yourself, but it will still show slightly and meet the 10 foot challenge of only being visible closer than 10 foot. For a larger area you could use a flow coat (gel coat with an added wax to make the surface go hard rather than remain sticky) and feather that in. The presentation I gave on gel coat repair has a lot of information that can still apply for you.

Although the information about a full repair above is ideal, you may find it cosmetically sufficient to deal with it only partially. There will probably be a mixture of shallow and deep scratches and it may be that dealing with the perhaps more numerous shallow ones by light sanding and repolishing will be enough to make it look presentable. Even after a year or two, just re-polishing over the deeper ones will make them less conspicuous.
