I am currently working on a set of maple and walnut bar stools for my wife. I am considering a shellac as a seal coat and a satin sheen varathane for top coat. I’ve read de-waxed shellac is best for seal coat but I can’t seem to find any suppliers locally that carry it. Is this going to cause a bonding problem? Any info would be great, thanks!

Sealer
Let me think ? Bar stools for the Wife ! - yea sure ......... I think the guys will be on them every Sunday watching the games.
A sealer can be the Varathane thinned down and applied as your first coat.

I'm surprised you haven't found a dewaxed shellac product, though the problem may be the way dewaxed shellac is marketed . The liquid form is Seal Coat by Zinnser. It only says it is dewaxed shellac in the fine print. Even big boxes often have it, though I have found it at many hardware stores. The other form hides in even stealthier dress. That is Zinnser areosol shellac. It's dewaxed also though the label doesn't say that anywhere..
De-waxed Shellac
I love de-waxed shellac, since it can be used under or between coats of almost anything. I prefer to mix small quantities, as needed, from flakes disolved in denatured alcohol (DNA). I get the flakes from Woodworker's Supply, which sells online. Various specialty finishing shops sell flakes, too. The flakes are said to last "forever" if properly stored, while the shelf life of liquid is said to be a couple of years. A small kitchen scale with a container allows you to weigh the right amount of flakes for the desired volume of DNA. A "one-pound cut" (good as a sealer) would be the equivalent of one pound of flakes in a gallon of DNA.
Thanks for all the input guys, much appreciated! About the de-waxed shellac...I'm not sure if it's just labeled differently in western Canada, but wherever I find shellac I can't seem to find it labeled "de-waxed"
If you find the product named Seal Coat by Zinsser that is what you are looking for, regardless of whether the label says dewaxed. But, I can't speak to whether Zinsser markets that product in Western Canada. Their marketing department is far from being competent.
I can just walk
across the street and get it at the local lumber yard. believe Home hardware also stocks it.
