Yeah...i was afraid the thing with the black ribs was gonna happen to you when you first showed it :-) You were to quick progressing before i had a chance to warn you...
If i remember correctly you wanted to do a CFRP-laminat from this body at some point anyway, right?
If i were you i'd not bother about getting the surface of this body buck to perfection because you will quite probably have to do it again on the laminat anyway...so why do it twice!?
