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

6kg!! That's heavy for a bonnet, especially for track use. This whole rear clam weighs 4kg untrimmed.



A BMW bonnet for a race car I would expect closer to 2kg.
