sealant
Bill,
Before I riveted my fwd fuse, I put ProSeal on the mating surfaces, especially on the lower skins. Just imagine a fuel or oil leak starting in under the cowl, and visualize it being blown by 200 MPH air out the bottom. It will show you where to seal. Definately around the firewall, the air ramp at the cowl exit and I did all my lower skins to keep airborne oil and fuel out of the inner fuse. I chose Proseal over RTV because PR can be painted, so any excess that I didn't get off, will accept paint.
