Clear non-yellowing finish for timber boxes.
Hello. I've searched the forum and found a couple of similar queries discussed, but I'd like to outline my specific needs in case it provides different answers.
I design and construct laser cut timber boxes for weddings and giftware. There is a demand for natural timber finishes as well as white. I'm looking for a clear finish that doesn't have a yellow or pink tinge when applied over white-painted timber. Is there such a thing? Due to the nature of laser cutting, it's necessary seal the cut edges of the painted timber to prevent chipping and moisture damage, and I would love to find a clear finish that I can apply to the entire box, not just the cut sections.
I had been using a non-yellowing floor sealer, which is fine on natural and stained timber, but it has a distinct pink tinge when applied to white. I currently use White Knight Crystal Clear Acrylic spray but have recently discovered that it scrapes off quite easily. Is there something more hardy out there that won't compromise the colour and which provides a tough finish?
Thanks in advance.

Yes, some finishes change colour with time more than others. All change to some extent. BUT all timbers change colour with time anyway. Don't fight that - it is a good thing. Our work should mellow and age with time, it is called developing patina. Nothing on earth stays the same. Oxydation and ageing are inevitable, like taxes and death.
On a more positive note, I agree with the previous response that the modified shellacs are probably your best bet. Sanding sealer may be another though I have no information on its long-term behaviour.
