Old cowling
When repairing a cowl I try to balance the repairs out and it is important to make the repairs look as if it is part of the original cowl or nice enough to make the cowl look better if not stronger and most important last. One thing is these cowl repairs are time consuming and it is not uncommon to spend 10 to 20 hours just repairing he cowl. In the case of my 180 I replaced the cowl doors with doors I made out of .032.
