What do you guys mean white streaks? does that happen after you scrap? do you have a photo of them? It's from places you haven't sanded through deep enough yet. Had that problem with the Kenskill. Had to go over them after the first coat of amber shellac and sand a little deeper. It's a tough nut to crack because too deep and you go through the veneer. Not deep enough and you have left over finish that was not removed causing the white streaks.

Are you saying any cabinet you add new coats to has to be sanded all the way to bare wood, or if you do sand, you have to get it all off?

If you have that white sort of milky yellow antiquish type finish often used with Birch then this is what happens. If what you start with is just pure shellac and there is no black water damage there is no need to sand all the way through. Make sure it's shellac though. Not all wood panel trailers used shellac. A test is in order.

I agree with Larry. The white streaks are where the wood isn't stripped enough, possibly old shellac, but who knows? If you can't see them, new shellac will look good. If you can, they will shine thru. Frustrating. Here are the streaks: I figured they would be hidden. WRONG. This was after the wood was scraped. We sanded the streaks until they were gone. A tedious elbow-grease filled job. Also, a cheaper grade of wood there. Pine??

Great thread! Vikx, do you sharpen your plane blade as you go?
