I am pretty much at this same point with regard to finishing. I am reading a lot of stuff, but it is difficult to understand (for me) the required prepping before applying the gloss coat. Things like sanding sealer, grain filler, and which is appropriate under what top coats, has my head spinning at the moment.
Let's say, like you, I want to use poly with no stain (to keep it simple). Firstly is that poly, one part or two? Easiest for me would be a one part poly from a rattlecan. Wipe-on also interests me.
OK, so what goes on the bare wood? Some type of clear sealer? Is this the "sanding sealer" or is it "grain filler" or something else? Is it, perhaps, better to just keep applying the poly, straight onto the bare wood, and sand flat every 2 to 3 coats, until the desired finish is achieved? How porous, or open-grained must the timber be, before some prepping coats are mandatory?
After a flat high-gloss surface is acihieved with poly, is further buffing recommended? Is waxing useful on poly, or is that just for bare or oiled woods?
These are just some of the questions I have
