Replace panels before or after dipping?

FIRST....

Please please please I do not want to get into the pros and cons of dipping a car.


My question is...

Would it be better to dip the car then replace the bad sections.

Or replace the bad sections then dip.

Needs at minimum

1. Driver's front foot well
2. Pass front foot well
3. Pass quarter behind rear wheel opening
4. Small patch (6" x 3" L shaped) under the top opening area on the pass quarter
5. Small patch behind driver's side rear most front seat floor mount

Dip first...

1. Find other areas that need replacing
2. Clean metal to weld to

Dip after...

1. Structural rigidity
2. All metal treated the same

Thoughts?
