Hairy PB is why you don't ask the dog to help make the PB&J sammies for lunch
As a tin build, it's more likely then not that you'll be using epoxy to make any filler needed to plug the dash holes. Mix an epoxy compatible material of your choice to make the epoxy into a thicker paste like consistency & it's more likely to stay where you put it. Rather then 'run' &/or drip out of the area you're trying to fill, the vertical face of the dash.... You could use saw dust, micro balloons or several other filler materials. Check w/ your epoxy supplier,
US Composites has several available, and it looks like most of them are epoxy compatible.
Hairy PB is usually associated w/ polyester resin that has fiberglass strands (the hairy) & other filler material (cabosil, micro-balloons, etc) mixed into it to make it more structural, rather then 'just' a filler. It's paste like consistency is similar to peanut butter. I don't suspect that you 'need' to add any fiberglass strand to the epoxy in your application. Since it's epoxy, it's already a stronger adhesive filler then poly resin, adding the FG strand will only make it even harder to sand. IMHO....
You could use fiberglass & polyester resin to coat the transom & fill the dash, but the mob may gather & rattle their torches if you do..
Poly resin alone isn't sufficient, it needs the FG reinforcement, or fillers.
Not much need to buy poly resin & fillers to 'just' fill the dash holes, but again, you could, mob not withstanding:watermelon:
White electrical tape takes a fine line sharpie really well if you needed to mark it's location....
Using a hole saw to cut similar sized disks of ply, securing them into the holes in the dash, and filling the voids w/ thickened epoxy should make a stout enough repair to tolerate a re-drill thru the new overlaid dash wood & original panel. Make sure to give the plug epoxy & the glue you attach the overlay w/ plenty of time to cure. A plug thru a 3/4" piece of plywood w/ epoxy filler may take a bit to fully cure. As would an overlaid lamination of 2 pieces of ply.
