I am just about to start re-building my Midas Bronze. It has stood outside for a number of years and the body colour (white) has faded and become matt in appearance. Any ideas for restoring it to something like the original, apart from painting it?

the best way to restore the gell coat is to flat it down whith 600 wet an dry then 1200 wet an dry then polish whith g3 cutting polish this is how it was done in the corby factory i have just done my mk2 and it has came out lovely

I'd be tempted to just T-cut it first and see how it comes out, then of course give it a polish.

I thought it was bad to use anything containing ammonia on gelcoat, that has always been the train of thought on the Quantum forum. I did a bit of my gold coupe that had been outside for 7 years with G3 and an electric polisher and it came up OK, plus it didn’t fade again after a couple of weeks, so I think I would try the G3 first with a polisher, you can always resort to wet and dry after if it doesn’t work.

Is this G3 stuff normal polishing compound of esspecially for gel coats? I have tried "commandant" polishing agent on my gelcoat to get rid of discoloured stains due to battery acid spillage. But the gelcoat is much harder than paint and I just couldn't get through. Also I have failed this way
getting a shiny finish on my gelcoat. It is not faded, but just looks like a plastic car. If there are special cutting agents for gelcoats, can anyone give me details of the product needed?

Hans, it is what bodyshops use to cut back normal 2 pack paint, it is made by Farecla, it comes in various grades, right down to one to remove swirl marks, it is good stuff.

Hi,
Does this work for the fine crazing that has got alot worse on my MkII? Just taken the cover off it today after a year or so and the gel coat is looking bad on the wings and roof. Heart braking afternoon.
It used to look like this :

Any suggestions great fully received.

I would suggest trying T-cut or Farecla G3 on a small area first to see how well it comes up. If that isn't good enough, then either try a coarser cutting compound such as Farecla G6 or 1200 grit Wet and dry, again on a small area and then polish up with G3.
If that still isn't good enough then try 800 grit Wet and dry, followed by 1200 then G3. The next step would be to try 600 grit etc.
If you need to do multiple experiments, then do them on different sections to avoid taking away too much gel-coat in one go. If you
cut back too much you will end up having to respray.
Finally, when you have got the gelcoat evenly polished up, finish off with a good coat, or two, of a protective sealer such as
Autoglym Extra Gloss Protection, or a carnuaba wax such as Meguiars.
These are purely protective finishes that include UV filters to stop the colour bleaching and will keep out moisture, which causes micro-crazing.
The waxes included in polishes, such as Autoglym's Super Resin
Polish, only provide short term protection.

Ive noticed there are a number of products designed for fibreglass
boats to revive the gelcoat. Some have 2-3 chemicals that u apply in
sequence supposed to remove chalking and then bring back the gloss. I
havent tried these products but their claims sound good. Has anyone
tried these marine related items for fibreglass??
thx, jim
