Being white oak it would likely darken the wood a tiny bit, though. The product line I was referring to earlier in the thread is called General Finishes High-Performance, also a water-based polyurethane, but does not amber like that. It ambers slightly with durability suitable for residential projects, and is both sprayable and brushable'. 'Enduro-Var is a self cross-linking polyurethane that looks more like an oil varnish than a water coating. The General Finishes website product says of the finish you used: They have a natural warmth to them and the wood looks beautiful. Maybe not 100% what you were going for but personally I think your cabinets came out top notch. It is also supposed to be water white and dry clear without raising tannins, you can get it online and at I see this was revived so wanted to comment.

Good Luck! One finish I found but did not try was General Finishes Flat out Flat, in water based formula. I will always wonder if I should have rolled the dice and finished them myself (to hell with the durability of a conversion varnish). I think I made the right call for me (we cook a lot and we have dogs, cabinets take a beating). It was a hard call, but that dead flat varnish was the only thing I found that would work and it was too thick for their sprayer (thinning with water just raised the grain of the wood). My cabinet shop found a light gray stain called Mountain Gray that is nice enough. But with a light scuff sand at 220 grit between coats and three coats. It goes on looking like milk, as it flattens out it darkens slightly, and when its dry you can't tell it is even there. I know of one product that does it, but its not made for cabinets. I was literally just going down this road.
