This is not a classic car, but I would like to achieve a long-lived result.
What are the relative merits of body filler vs seam sealer in general rust repair?
1. How large a void can seam sealer be successfully used for?
2. Which is more finishable (sanding, painting)?
3. Which seems to work better for adhering to and filling relatively flat surfaces?
4. Does either provide a better life-span with patches?
