Looking at Sanding Sealers there appear to be three main types differing in the solvent they use. I am wondering what advantages or disadvantages there are between the cellulose, acrylic/water and Shellac based sanding sealers. They appear to be about the same price and I can only guess that the choice is related to what you are going to put on afterwards, wax oil etc.
I've tried a web search but haven't found the usual plethora of helpful sites! Any ideas please?
