So I finally got one! I heated it and the moisture out

A few quick questions

1. The gun isn't worth a rib relay, so is there anything I can use to seal some of the spacing in the solder?

2. The water that did drain out was clear, so I dont think there is any rust issues, would it be permissible to get some oil under the rib to help protect the barrels between the ribs to inhibit any rust that may form?

Thanks
Rick
