Like some other HOC members I have been searching for some time for a gelcoat repair kit which would enable me to undertake minor repairs to the blue hull of my Seawings 234. Hardys long ceased to reply such an item. A fellow member, Graham Green, who works in the paint trade, suggested I approach CFS Fibreglass at United Downs Industrial Park, Redruth, Cornwall, TR16 5HY. I did so and CFS have supplied me with a small tin of their clear gelcoat and a tube of the appropriate pigment. CFS's website is www.cfsnet.co.uk/ They may be contacted at sales@cfsnet.co.uk, Tel: 01209 821028, Fax: 01209 822191.

You can get the gelcoat repair kit from Hardy Marine, I purchased one for my pilot easily in october 06.

I've just done the entire hull of our Pilot 20, using an electric mop polisher that I got from ASAP for £20 - best thing I ever bought. It effortlessly removed the oxidisation using cutting compound and then applied a good quality wax polish and now Daisy looks very good.

Thoroughly recommnded.

Just a thought for some of you . You will find that most batches of gelcoat are often slightly different in colour, even if you get the stuff from Hardy's themselves.

Also often with normal fading seen even after polishing , this difference between new and old can be noticeably different on repairs.

Recently i overcame this problem by visiting a profeessional paint shop and after leaving them a sizeable deposit , borrowed their Du Pont colour swatches, which incidentally gave me about a choice of 250 shades of blue around the hardy colour.

Anyway using the swatches , i matched and then had made up an aerosol of paint, 2 pack profeesional with hardener( B3/B250 ) which has 2 uses.One is I can use it to touch up light surface rubs and it blends in perfectly. Secondly , I have sprayed up my own swatch which i have used to get a local dealer to blend me up some gelcoat to match .

A long way around to get a perfect colour match I know , but when you cannot take the boat to the people who are blending the gelcoat, and there is nothing to take off to send , it seemed like a good idea.

Just one note of caution , professional made up aerosols with hardener , have to be used in one go as soon as you activate the hardener.of course 2 pack paint can be made up into aerosols without the hardener and I am sure it will be ok for most above waterline useage.

Just a thought for some of you if you are as fussy as me and like everything to be perfect.

Congratulations on devising this solution.

I got a Gelcoat repair kit off Hardy to fill minor scratches on my Fishing 17. I stopped using it as the repair just made the blemish more visible. Particularly true when the hull faded a bit.

I have a gouge in the blue topside band on my Pilot. Instead of filling it I have covered it with a piece of matching blue insulating tape. Is is only detectable if you are looking for it.

The bloom is the oxidation that happens on all blue Hardys.

Any rubbing compund is ideal for removing it. I have also read that you can use very fine wet and dry (used wet) to get rid of this in particularly bad cases.

My own thought is to use the least drastic technique possible and I always get excellent results with rubbing compound.

Thanks andy ,

I think that if you try machine polishing with a number 3 cutting compond and then finish with a hand polish using a number 10 cutting compond you will get rid of any oxidisation marks without resorting to the wet and dry method , which in my opinion would be a very extreme measure indeed.

This is how I have always polished my current and previous Hardys, and then finishesd them off with a couple of good coats of hard wax, (old fashioned simoniz ) or even a proffessional glaze wax as used in the auto trade . Works a treat , and if done properly will bring back and maintain a 'as new'finish.

Does anyone know the weight or volume ratio of hardener to resin for Hardyís own blue gel coat repair kit?

Unfortunately the label on the small bottle of hardener I have is damaged and no longer shows this information.

Most gelcoats tend to be a 2% mix, though this does depend on temperature, whether thats the same as yours I have no idea. You could try a 2% mix and see how if cures, You'll ideally need 15 degs C temp outside to make it set well.

Might be worth having a read up on www.cfsnet.co.uk

Hi I have just joined H.O.C as I have made my first purchase of a Hardy 17 fishing boat.
The boat is in great nick but has been stood up for the last 20 years so the blue gel coat has faded but it sounds like a rubbing compound and a good wax should put this right.

This boat has a small cuddy on the front, I would like to put a small windscreen on top of the cuddy to raise the head height so I can add a spray hood anybody got any ideas were I would get one from?

Welcome Paul

Nice purchase, and a nice boat - I always fancied an HF17 and rigging her with twin 25's for fun!!

Gelcoat wise, yes, gentle compound - nothing too aggressive - then, once she's shining again, get a good couple of coats of decent wax (cheap wax just washes away) on her (3m or similar I would have thought), Then, if she's kept ashore, I'd suggest giving her a max every few months - that should keep the chalk at bay.

Ref the windscreen - Wilson Flyer boats should have a good FRP moulded design (I seem them online sometimes) - I think with a small roof, and another without. If might take a bit of fitting, but is probably one of the better options - it should look the biz when done. see: https://www.facebook.com/wilsonflyerboatsuk/about/

Failing that, Orkney boats might have some moulds and shapes that could be a near fit - so perhaps have a chat with them too.

Otherwise, you could go for a bespoke unit - have a word with J-Star boats (add in the forsale section), Mr Papendick who runs the business probably built or worked on your boat when new - so He'll know!!
Best Regards


Best Regards

Many thanks Simon.

Hardy club membership paying off already, have been in contact with J-Star boats and spoken with Simon he has agreed to come and look at the boat after Christmas with the view to making one for me.

Great result thanks again Simon.

Regards Paul.

After the blue hull on our Hardy Pennyghael had been professionaly restored ( see Hardy Owner Number 127 ), it was suggested that we useTurtle Wax Colour Magic Colour Enhancing Polish Shades of Dark Blue. This we have done and found it to be very successful. The bottle we purchased in our local car accessory shop had a free Chipstick rather like a lipstick, which has been excellent for filling in scratches. Altogether a very useful tip.

The Hardy Gelcoat was good quality, it's great when you get that deep shine!! Wonderful job.
