Wipe-on Poly on Huon Pine: Problems

[Rattrap]

I have read of issues with poly over shellac. From what i have read its the wax in the shellac that can cause issues, this is why dewaxed shellac has been recommended, plus it has the advantage of keeping the HP colour rather than yellowing it.
Ubeaut sell a good dewaxed shellac.

Personally, I would stick away from plastic finishes such as any sort of poly product for items such as these bowls, and agree a shellac and bees wax finish or alternatively tung oil, or organoil finish with waxing afterwards is the way to go.

Huon Pine, will always with age go yellow, that is the natural colour for such a timber, and I wouldn't fight it. IMO it looks much better anyway than the original cut and finished light colour that you get from a new piece.

Again, unless you wish to coat over a shellac finish with something like a poly product I see neither any advantage or necessity for a de-waxed shellac. Frankly from my experience, I have never needed this, nor if one were to wax it anyway once finished or if you were to use a oil based finish such as Tung oil etc can I see any logical reason why you would wish to use such a shellac. My $2 worth. Dave
