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 prototype (not like ill change mould features) in terms of layup, cut lines for louvers and fittment. Still if i can sell it to cover material cost (plus moulds) that would be great

ATM its sitting just over 6kg (with glued in features like bolts and screw points) and its surprisingly stiff so for track/race use i can drop weight by 1 kg at least from inner part.

I learned few new things like:

-build bigger owen
-100% clean mould before putting part back in
-dont use 650g cf as 2nd layer unless you want big print trough (tho after mild sanding and clearcoat ut should be ok)

As always thanks for your help
