Hi

I’ve a 2009 Jeanneau Prestige 30 that has had some minor impact damage on the topside which has created a spider grazing over a hand sized area (original owner did it!).

I’m guessing the original owner either applied some “dressing” or repair of sorts that covered it up but it is now starting to show through again.

Is there a treatment that can be applied to mask it a bit more - a thick covered dressing / a heavy wax?

Any thoughts?
 
You will need to grind out each craze and then fill, either with matching gel coat or epoxy that will need painting to match. Trying to just refill the cracks will not work as they will crack again.

I recently bought some. Yet to apply it so cannot verify it's effectiveness but thought I'd give it a try on some spiderweb thin fine cracks I found near a bow cleat. No idea where or how the crack developed but it is so small it doesn't warrant a full repair yet but bugs me still.

Bruce, I'll be really interested to see how you get on. I've a few hairline cracks that aren't worth raking out and filling but this could be a good solution.
 
Interested to hear how it goes. I tried it last year with limited success. It seemed to pull away like a thin rubber string. Probably me not cleaning the area sufficiently. I resorted to grinding out and filling with gel coat.

The reviews on Amazon aren't very good either

3.7 out of 5 which imo is a good score especially as those that rated it 5 star showed pics which impressed me. Of those that dissented half was about colour matching and the other half didn't apply it correctly reading between the lines. Suggest watching the manufacturer videos. They do say it must be applied in +20C temps or use a hair dryer. I've applied gelcoat in colder temps. It set terribly. Doesn't make gelcoat bad.
 
Hate to spoil the party and I really would like a simple fix as much as the next guy, but I'm not hopeful you'll find a more long term solution than chasing out the cracks back to grp and filling with colour matched gel coat.

Fully agree. But as my cracks are spider web thin and maybe 3cm long at this point in time I'm happy with a temporary fix until such time as it becomes a worthwhile job. I just want to seal the crack for the moment and if it hides the crack all the better. I'll take some pics when I get round to it, before and after and we can take it from there.

Fair enough Bruce, but the cracks will go all the way through the gel coat, thin they may be, but all the way through I assure you they are.

Looking forward to pics though.

Just a thought, milliput superfine white might work well. It is a two part epoxy which I used to repair small crack in a classic car bakerlite steering wheel. It is applied by hand and water to make a very smooth paste, worked well for me. It comes in a few different colours.
 
Hi,

I had a 'bump' courtesy of a neighbour's anchor with a palm sized crazing on the upper part of my Jeanneau.

I channeled out the crazing, then filled with gel coat supplied by Jeanneau.

If you ask your Jeanneau dealer, they can arrange for a pot of the peculiar off white gel coat that Jeanneau use to be sent over from the factory along with some hardener to mix in. You mixed the gel coat and hardener together, fill the channels, then you must cover with some tape so the process will go off properly. 24 hours later, take the tape off and sand back with wet n dry and then some polish. It worked a treat and very difficult to spot afterwards and not such a difficult job. But getting the colour matched gel is key here if you want a near invisible mend.

I second this, super easy and perfect results.

not when it's across non skid though.

Did not know that was what this is about but either way still quite doable, use a dremel or similar.

Generally and in my humble experiance one will get gelcoat damage every year and getting to grips with proper repairs (if one is diy inclined ofcourse ) will be very useful.
