Prolly too far to go (eastern midwest) but....
There is a guy here in Cincy that dips and strips...
He's an old hot rodder named James Taylor (not the rock star).

He did my front fender and rear trunk for $65.00 apiece. Not cheep but good. Usta reach under the trunk to lacerate my hand on the rust.
He was able to convert the rust bubbles spreading the folded seam, eliminate the rust iunducing foam pad in the trunk and provide me with a rust inhibited part good for 3 months untreated.
One visit he was dipping a whole model -T into a rust removing "swimming pool". Seen engine blocks, car parts, yard furniture, you name it coming outa that pool.
Asked whole car price, he hesitated as all rusty cars are different. Ballpark number was approx. $1000. Model T looked great.
Dang, not only do I know James Taylor, but I worked with John Holmes
Was John really an Optical Physicst?
