Filling holes

[mickter]

Looked at a ally hulled Rib,want to move console and seats, what is best to fill holes left by removing rivets,(ally floor)
TIA Mick.

New rivets would be the quickest and easiest method. A bit of sealant like Sikaflex around them, fit and wipe off excess. Not the most cosmetic so depends on the desired finish but a robust fix.

Smoother finishes viable using an epoxy but without being able to get to the underside they are likely to pop out eventually.

Countersink, drill and tap. Fit 4mm? Stainless allen screws.

Won't you be risking galvanic corrosion?

Best of all, weld them up and grind flat

In theory yes, reality I doubt.
TIG might work but can't afford to put too much heat into flat sheet

Or a squidge of zinc chromate paste. But either way, I reckon closed end countersunk rivets is a practical way to go.
