Used stix for the first time on a whole house interior trim job. All the doors were solid 6 panel, stained and lacquered. The frames and base were a intricate profile with many grooves and detail. Prepped and sprayed doors in garage. Plastic, paper and plastic film on all walls furnititure, floors, etc. Two coats of Stix. It sands beautifully and allows for great adhesion of paint. Two coats Advance. Excellent results.
