I’m trying to refinish the above table but having problems with streaking polyurethane. Using Minwax Fast Drying. The process has been as follows; sand, stain and applied poly using a Purdy brush for oil and following the directions on can. The brush left terrible brush marks.
Waited the recommended time and lightly sanded until smooth with no visible marks and put another coat. Looked terrible. I’ve tried recommended foam brush, tried rub on method by diluting poly with mineral spirits and the last attempt was with 100% Lambswool applicator. As you can see in pic still looks bad.
Could it have something to do with the way I’m sanding. Used a dewalt sander starting with 80 grit sandpaper and ending with 220. Although on the last few coats I used 320 and 400 doing a hand sanding just don’t know where to go from here other than Starting the process over. We bought a sprayer today hoping that would help.
All suggestions welcomed If you enlarge photo may can see better. This was taken in garage and only half of table is getting full natural light
