Spent 5 hours painting two doors. Our back door has nine glass windows. I CAREFULLY taped the glass so I could paint the panels. Taped the locks and knobs on both doors. After 5..almost 6 hours of work....Each with a coat of primer......The front door with three coats of semi gloss black and the back semi gloss white, The WONDERFUL tape pulled paint from around the front door lock and the back door windows are an absolute disaster. Paint seeped under the tape in many places and just about every pane had paint pulled off. SOOOOOO...Tomorrow, I'm just gonna scrap off what I can around the windows, paint and scrape off excess with a razor. And touch up the front door.
