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

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.

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? Edited 13 Years Ago by Ragece

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 also used it with Unimold system, and its proven to work perfect (I use 6 coats of wax, no easy-lease, no pva). So I'm with Ragece for the polyester paint. Much more thin, perfect for molding an existing part. From my experience, I would highly recommend a test panel before you proceed to your final part when you get new products. Chemistry is sometimes a bi***. I know it's one lost day of testing but it can make the rest of the week go better I got a question about your part: saw you used spray glue to tack the fabric to the mold. It may not be clear in the pic so: does your part have cosmetic "residues" from the glue? And if not, would you share the brand and type of glue. Thanks, and keep us posted with your new parts A $1000 electronic device will always protect a 10 cents fuse
