I will definatelly have to look into getting some of that polyester paint... have you used it with vinylester mould systems as well?

Nearing completion of the mould... only returns on the wheel arches to do as per the last pic.

Also made another Binnacle as self training, use pro finish and I am stunned how good this is and workable... so much so I have ordered a load of it so I can do the entire first layer on the clip in it.... as a result the lines of the weave on the binnacle were flawless and the end part was significantly better than the first.
I still had a leak which resulted in a few dry patches of weave in very outside edges, no voids though as I stuck the carbon down with spray adhesive... I think this part can be used when it is properly laquered but Im still going to make another just as more training and this time I will totally bag the mould as I believe the mould may have a pinhole leak.

I used to make molds from parts but maybe not as big as what you've taken on. I ended up spraying all my parts with a polyester type paint specifically for bucks - it didn't react with most of the paint finished. It could be sanded and polished to a mirror shine and liquid release agents used on it also, it made getting molds a lot lot easier and the finish of the part was A1 with no work needed on the mold. The guys at SP systems on the isle of Wight commented on how good the finish of the molds was and that i must have spent hours polishing them. When I told them I hadn't touched the mold and had simply applied release agent they didn't believe me.
 I also found leaving fibreglass molds on the buck for 3~4 days helped them retain shape and size considerably better, early release ended up with misshaped molds as the resin is still curing. 

You may need some frame work adding to those molds to keep them stabilised?

unfortunatelly an area around the number plate reacted behind the gel coat... I looked at it the next morning and it was dry and fairly localised but I wasnt happy... when I returned to it 15hrs later it had spread to a larger area and separated.

Its also happened to a lesser degree in the light recess, but as this is has the light in Im not going to rectify this and will just make do by repairing in the  mould.


I decided to remove the gel coat in this area and the paint came away... i'm now faced with an area of gel coat to redo which is onto a less than perfect finish on the buck.

I think I will have to gel it again and then repair the finish in the mould otherwise I could do more damage to the ret of the buck removing the rest of the gel coat... its not a disaster, just very unwelcome.... 

amazed that its so localised... could have happened over the entire thing so I guess i should be thankful.

any ideas as to cause... the top coat was 2 pack and primer has settled for months.

mould of rear clip is taking more time than I expected... It took 7 hours to do the final filler layer of 4-5 layers of 450mg matt just on the top... or custard layer as my mate calls it lol

separated one of the wheel arch vents... wouldnt normally but needed to prove to myself that it was going to come apart and I wasnt making silly mistakes that would destroy the buck... well they came apart pretty easy with a very strong mould section and great finish Smile

The binnacle took 3 days to cure lol... anyhow even though the bag lost pressure and the small flanges on my mould meant i couldnt get the core materials right into the edge I decided to go ahead with the pull regardless as it was going to be 5 days before I could have another go.

well the part is significantly better than I expected, I learnt a lot and it is possible with more care I might be able to use the binnacle mould to get my final part.

Hi ,


One other tip i have is when you make the molds make the flanges where the bag tape is going bigger than you think

I have remade some molds and have done this it makes bagging up SO SO much easyer


ATB Daz


your parts look great look forward to seeing more

must say after making 1 part I already 100% agree with your advice and going to make the flanges 3 times the size on all new moulds i make Smile

one question... how long does the resin take to cure?

Hi ,

I havnt got a thread im waiting to finnish all the carbon and then do a build thread,

One other tip i have is when you make the molds make the flanges where the bag tape is going bigger than you think

I have remade some molds and have done this it makes bagging up SO SO much easyer

It may be that im a novice and a pro would get on with smaller edges

But with the carbon ,kevlar,peelply ,infusion mesh and bag i found it too tricky

Its nice to be able to tape stuff down and have a nice clear edge to bag to

Here is a couple of pickys dont want to clog your thread up :-)

Roof just out of mold



One of the arches





The wings are going carbon as well but im still in the process of fitting wing vents to the original
