Hi guys.

I ran into a bit of a problem today.

So i made e46 m3 hood. All good except for a little bulge (located in middle kevlar/cf "island on the right side o)n the top side (that i didnt notice untill todat when i took glued item from top mould) :/

After mild postcure (sun so max 50*C atm) it came out great so somwhere from that point to prior of bonding halves together this happend (inbetween i was only cutting vent holes).

Stack was as followed (top part) :
-245 2x2 cf
-600 2x2 cf
-200 cf/kevlar

All this time (apart from cutting & triming) paet was laying flat in mould to awoid any accidental damage in workshop. 

Halves arenow bonded and i can not seperate them again.

I was thinking of heating it gently locally with heat gun and then put so soft weight on and let it cool of (as atm TG is quite low...... plan was to let it full post cure bolted on the car and then sand it and get it clear coated). 

Any ideas how this happened and any alternative ways to solve it?

Thanks a lot

Well OEM alu sits at 10.4kg.

Top half weights 2.5kg and its 1mm thick. This bonnet is quite big as i just managed to get 1.5m cf cloth to fit

OEM closing mechanisms will be used and with these you really need to push a bit on the hood (i imagine something much thinner would just warp to much).

Ill post more pics (including guns ) once i try to correct "island"
