The I'm-Learning-As-I-Go 1965 Valiant Post
Hi Matt! I see you posted up,and Im glad you did. Lots of engouragement here for you. As for the rust,het either you buy a mig welder and teach your self how to do it or pay someone.
Maybe get a job in a body shop? to help you learn some of the skills for cutting and replacing the rusty area's. Or perhaps Bob knows a thing or 2 about body work. Honestly it's not hard,just labour intensive. Dont let the rust scare you. Thrown a cover or something over your car. Get a good water proof one,or a water proof tarp. This will at least limit the damage.
Do some searches here and you will likely find many restoration threads full of advice on metal working,body work,painting etc. There are MANY DIY A body guys!
