Which do I need...

[standfirmrasta]

In order to eliminate these scratches do I need wet/dry or will a cutting compound suffice?

Which grit or compound will I need?

Thanks.

PS I know they cant be seen on the water but with the boat on the hard now I can see them and I tend to be a bit a_ _l about appearance.(pride I guess)

polish out all of those with Farcla G3 then G10,thanks to Farcla for the instruction below always use lots of water whilst polishing,
There are experts on here who will no doubt add some input shortly


Working with a Polisher

Polishing machines will make the compounding application much faster and will also give a better finish. These can be hired from either a tool hire shop or possibly a boatyard. Do ensure that the machine is suitable for polishing i.e. not a grinder, as the speed required to polish is very important. Approximately 1800 RPM free running is the optimum speed but certainly no faster than 2000 RPM.

A small amount of compound is picked up on a clean cloth, the lid replaced and the work area lightly dabbed. Most people use too much. Only a little is needed to do the job; any excess flies out and has to be cleaned up afterwards.

For best results use a damp foam compounding head (Advanced G Mop). Before use soak the compounding head in clean water to ensure the water is inside the foam. Spin off the excess water in a bucket or bin. Position the foam compounding head onto the compound and gently move the machine. This action spreads the compound on both the surface and the compounding head.

Start the machine and move it steadily backwards and forwards over the gelcoat. The compounding head should be held at a slight angle to the surface; at between five and ten degrees.

When all the sanding marks have been removed and gloss begins to show through, ease off the pressure. You can add more water to the surface without any more compound to give the best gloss. Final gloss and blending in is obtained by running the machine quickly and lightly over the whole area, using the flat face of the compounding head and less pressure.

Wipe away any residue and buff with a soft, dry cloth.

On dark colours, it may be necessary to follow with an application of G10 Extra Fine Grade Liquid with an Advanced G mop Polishing Foam. The same instructions for use apply.

Protecting the surface

To protect the work you have done it would be advisable to put on a coating of wax. Protecting gelcoats and painted hull surfaces against dirt, oil and extreme climatic conditions not only enhances the appearance, but prolongs the life. A non-polymer, non-silicone wax polish is easy to apply and causes no problems should any repairs be required.

Not classing myself as an expert (although i have used the odd spot of Farecla compound over the years), but i'd agree with you.
