Hi everyone!
New to the bodywork forum, but I do all my own mechanical work on the car. After 10 years of ownership I finally decided to strip it down for rust repair and a full glass out respray. I am doing all the rust repair myself, and it will be up to the bodyshop to make everything look pretty at the end.
The car has very little rust, except for a few of the common places: windshield corners, fender/tub/cowl joints, and where the upper and lower B-pillars meet.
I should mention that I have a TIG welder and decent skills using it.
My noob question is as follows: how bad does rust pitting need to be to justify cutting out and patching an area? As an example, in one windshield corner there are no pinholes, but quite a lot of deep pitting (see pics.) I can’t grind all of it away or the area will likely get too thin. However, I definitely don't want to have more problems in a few years. I'll patch if I have to, but this type of fabrication is new to me and I'm not well equipped to make complicated or curved pieces.
All advice welcome!
