NO !!! Not unless you know the history of that old metal. Same story as my 1948 Starlight Coupe.So I'm about to get started working on the bottom of my Studebaker boat and I have a question. There is already flex seal, paint, and other materials patching the bottom. Should I strip and sand it off before putting my own sealer on it?

There was no BONDO In 1948, no resins, no exotic sealers, primers, clear coats, etc, etc.
They used LEAD as metal fillers, ACID-primers, OIL-enamels, lots of elbow-grease !
Any bodyman will tell you NOT to strip away the old finish, unless needed to repair the metal. Today, they use modern sealer-primers, modern acrylic paints, hard-coat glazes that last forever. $600 for materials. OR,,, grab your sander, grind the crap outta it, and your new body-shop estimate is $1800.
I helped restore an old green Sears Game??Fisher that had laid in mud for years.
Probably the most gentle of abrasive-based blasting methods, and rinses off with water.We had it SODA-blasted, which will not harm the metal. No sanding req'd.
All above very good advice!The painter used a two-part epoxy paint, $$$, (lawn grass green) over the cleaned bottom. The inside was pressure-coated a slate-grey 'rubber-coatng' used by the auto industry. We dryed it with hair-dryers :>)
REALLY good advice! Many body finishes today, both marine and auto, have chemicals in them that can even be absorbed through the skin. Pay VERY close attention to safety precautions on labels or the MSDS.Note: All work had to be OUTSIDE. You cannot breathe any of that stuff !
I just acquired one of the Vio Holda boats today and would love to pick your brain about the company's history if possible. [email protected] is best way to contact me.Hey Greg, thank you for appreciating something that my great grandfather built many years ago! I don't know if your still on this site but thank you! I just acquired 1 myself and am in the process of restoring it.. I am very excited!
