Be a little careful here.

I know of a IVP that lost the cowling on an early  test flight -  probably
(IMHO) due to the hinges coming loose.  These were aluminum and were riveted
on - not bonded to my knowledge.   Bottom line -  whatever you do - make
sure they are well  secured.  Luckily the test pilot was able to land the
plane in spite of damage to the tail assembly as the cowling halves departed
the airframe.
