No, there were other moulds in the oven that didn't got the color
The part was fine out of the mould but its just strange it looks like this

Very strange.  Did the oven go higher in temperature for some reason?

Mpulds are stil working good only weird thing I got is one mould the gelcoat is turning yellow to brown in color .
I took a picture of an other mould on it ,both made the same way  I got arround 10 eg160 moulds and only one  does this .

The one that turned brown only had 1 part pulled from it and the other arround 5 parts

you could have some surface contamination or maybe an old resin that has not cured properly/not achieved its designed mechanical properties.  Although both of these are so rare I have never heard of it actually happening although it is theoretically possible.

Sounds like you left the gelcoat a little too long at the b stage before overcoating. Generally that is the main reason you could have delamination between gelcoat layers.

Everybody stil in Holiday ? 
:p

Stil nobody more info on the 2 layers gelcoat?
Made a new mould with 1 layer and  found the only negative side , you need to let the gelcoat cure longer and wait longer for demoulding  so you wont get print true of the weave .

I had a new part tested today I added a layer of XPREG XC110 416g at the mounting poits of a part so  2 layers of XPREG XC110 416g where the part is bolted to the bike and I got pinholes only at the place where it has the extra layer of XPREG XC110 416g

I used the same on the unimould as on the high temp epoxypost cured them the same and for the prepreg  . 4H soak at 70° 1H post cured the mould the same 
Only issu was few pinholes where you put the bolts thru the fender when mounting on the bike . 
But thats more a bagging error from myself with the new parts in the high temp epoxy I had the same on 2 of the 4 parts just looking to get the bag down arround thos spots is sometimes a problem .
