Hi Bob

I would think the high density filler is a bit overkill for general bonding and filleting, it gives a really nice smooth paste but dries very hard, you can shape it with a file. Unless you get your fillets really clean right out of the gate they will be very hard to sand with a HD additive. This is what I typically use for everyday boat building applications:

404: Bonding hardware pockets or high load joints, for example transom laminations or knees on an outboard boat. I used this on the Stapley restoration.

405: Any wood bonded joint that will be bright finished and therefore may show the glue line in the varnish. I sometimes also tint this with a bit of mahogany dust as its natural colour is more like ash or pine. Bear in mind that 404 or 406 can go a yellowish colour in time if varnished over. Not a great look and even a line between plank edges can show this... Miss Isle has some 😉

406: Most general wood bonding that will be painted not varnished. 

407: Filling, fairing and filleting on any surface that will be painted.

If you are painting the inside of Temptress then I would use 406 for bonding and 407 for filleting. If you are planning on a varnished finish inside then I would use 405.

Hope that helps.

Thank you.  Very thorough explanation!

And perfect timing, as my outsourced CNC layout boards were completed today.
