In theory, with Rubio you can do some localized sanding with 220 and reapply Rubio to the area….but if it were me, I’d sand the table entire top to 220 blending in the extra sanding that it will take to remove burn marks…then reapply Rubio to entire top. I started using the universal maintenance oil on top of the Rubio pure for a little more sheen and really like the look. I believe that Rubio will tell you to only sand to 120-150 but I’ve always sanded to 220 because I can’t help myself and I’ve always liked the finished product.
