Farcia G10 - G3 Paste or liquid.

What does the forum recommend for bringing that shine back to the hull.

Or are there anyother products which will give a nice gleam.

we have only used 3m in the past.

The G numbers refer to how much abrasive is in the mix. The higher the number the more abrasive. If you use G10 and a blue wheel, you will go through the gel coat quite fast!
G3 is a real polisher, so choice is totally dependent on whether you are doing it be hand, and the state of the Gel coat. Im using G3 on my 22 yr old hull.

Thanx for that talbot.

The boats only six years, does not really need cutting only polishing, so G3 sounds like the one i'm going to need. Iv'e just bought a proper polisher from machine mart. So any tips on how to get a professional job would be most welcome. Do you use the paste as well as the liquid ? And what sort of quantity am I likely to use for a 38 foot yacht.

I don't think you are correct in stating that G10 is the coarsest as I believe it is actually the finest and is used for finishing after using G3 or G6.

Out of G3 and G6 I do not know which is the coarsest, or if there is any difference in that, excepting G6 is recommended by Farecla for harder surfaces (such as polyurethane paints) and G3 for softer ones. Perhaps there is no difference in coarseness but just in the particle shape/material, but I do not know. I haven't cracked the G codes yet and I would be interested to hear if anyone has.

We use, and were recommended to use by the painter, G6 for our polyurethane paint system. I have seen other forumites saying they use G3 on gel coat and that, being softer than polyurethane (my assumption but think it would be so), is probably the correct choice. My understanding is that G10 is finer than either and can be used as a finisher.

Have a look at the <A target="_blank" HREF=http://www.fareclausa.com/chart.htm>Farecla</A> site for the answers to some of your questions.

Thanks from me too.

I didn't realise they had a USA site as well - I think that site answers my question too thanks. G3 is actually the one that cuts most with decreasing cut to G10 which is the finest.

I used G3 liquid on my boat which had stood in a corner of a boatyard in the Med, unused for 3 years. Used a slow rotary polisher with a lambswool mop.

Boat came up an absolute treat and will only need a very light rub over with a conventional polish to be ready for the next season.

I'd start with G3 and if not course enough (I'd be surprised) move up.

Thorough recommendation here, just make sure that you have a slow rotating polisher.

<<<I'd start with G3 and if not course enough (I'd be surprised) move up.>>>

It would seem from Farecla's USA site (unless they have got it wrong) that G3 is actually the one with most cut, G10 the finest with the least and others in between according to number, so it is not possible to "move up" in coarseness from G3.

Sorry, you're wrong!! G10 is a liquid and G3 a paste, recommend G10, have used it for years with excellent results.

G3 - Advanced Rubbing Compound
(High Solids Paint)
#01009 - 1 Liter (34 fl. oz.)

For rapid removal of dry or wet sanding marks for all paint systems including High Solids. Ideal for use on tough compounding jobs (hard paints) or where speed of cut is particularly important.

G10 - Advanced Rubbing Compound
(Extra Fine Finishing)
#05008 - 500ml (17 fl. oz.)

Extra fine grade for creating a smear-free ultra high gloss final finish. Removes swirls and fine sanding marks permanently by hand or by machine, so that no glazing is required. Particularly designed for use on dark colors. Also useful for blending old or new paint work to match gloss levels.


SO USE G3 FIRST FOR HIGH CUTTING THEN G10 FOR HIGH GLOSS FINISH.

THIS IS FROM THE FARECIA WEB SITE ???

silly me - knew that G3 was high polish, and that G6 was high cut and assumed there might be some logic to this

I had never worked it out until today after the Farelca USA link was given and that made it clear.

Will feel much more relaxed now laying into our boat with the G6 as I sort of pussyfooted around with it a bit before fearing that it would be more fearsome than the G3 and take all the paint off /forums/images/icons/frown.gif.

and forget it without a polisher.
G10 really is for that super high finish. It brings up the gloss, but i think you could polish for hours without it turning matt to a shine. Cant say I could notice much difference between G3 and G6, when cutting back. Might be tradestation.com or something similar had these products much cheaper and free delivery. get a few extra sponges because they shred pretty fast if you catch a cleat or fitting!

Dont forget that Screwfix sell large bottles of Farecla and all sorts of polishing heads and mops at a fraction of chandlers prices

More tips,

Hang the polisher by shock cord from the main halyard when using it - this makes it much easier to manage
Use tresles and planks around the hull - its difficult to use a polisher on a ladder
Use a squeezy bottle with water to keep the polisher head wet
Wash the hull first before polishing to get rid of any grit

Thanx bluechip. Just been flicking through the screw fix book.

Assume you must keep the hull wet to keep the friction low and stop it burning the hull.

Yes agreed. Talbot has it the wrong way round. Just bought some G6 and G10 (the final polishing one) for my topsides.
