Default Re: Polyurethane Sanding Question

I had waited 24 hours after applying the spirit dye before applying the sealer. I mainly used the sealer to try and fill the grain, it does a reasonably good job of that. I did notice a bit of dye on the brush when applying the sealer, so perhaps it interacted with the dye.

I did buy some "thixotropic"(?) grain filler, but I found it difficult to work with, it dried VERY quickly, and the dye in it was darker than I wanted. It seems difficult to fill the grain on walnut veneer if you want to use another dye, the thinness of the veneer is also challenging.

Hopefully I'll find a combination Im happy with. Its a good thing I have lots of veneer left over from the main project (record changer plinth), so I can test so many different products and methods. Ive had all sorts of lashed up projects and PCBs hanging around the workshop, so it makes sense to make boxes for them. I also have lots of ply offcuts Ive squirrelled away from DIY projects
