hello, just started cleaning up the windshield surround and discovered significant rust, (there was just a hint before i started grinding, pictures are posted). what's my best approach? i've worked with fiberglass and thought maybe doing that from the inside would be the easiest? although recently i got a mig welder and that's an option, (just learning how to weld see picture

). would appreciate some direction from preparation, to painting. although i have had several classics, this is my first attempt at restoration. my biggest concern is making the cab "weatherproof" before winter. any and all input will be appreciated. ~m[b][/b][i][/i]
