I normally use Velvet Oil and top it with several coats of wipe on poly but when I want to retain as much of a white color as possible I’ll use a water based poly. The problem is, no mater what I use to apply it with I can’t get it to flatten out. I either get brush strokes or streaking if I use a foam applicator. I am careful not to over brush and I have used just about every brush out there to eliminate the strokes. I am wondering if anybody has any suggestions on how to solve this issue. The next time I do this I think I might use a thinned shellac. If I go that route can I thin the shellac and wipe on as with the oil based wipe on’s? Thanks for any suggestions you may have.

Try applying the finish with a boars hair brush. To eliminate brush strokes hold the brush at 90 degrees (straight up and down) With just the tip of the brush touching the work piece.

For waterborne polyurethane you have to use a synthetic brush. Keep the brush wet as you work. Also consider spraying it. I’ve had good luck using rattle can Minwax.
Good luck!

I never get brush strokes when I spray, just sayin. No help at all for brushing, sorry

The answer to your shellac question is yes: I cut Zinsser Bullseye Shellac 1:1 and wipe/rub it on. It dries almost instantly. Don’t try to lay on a thick coat. Black Cherry has a good blog on rubbing on shellac that has worked very well for me.
