Our door needs some attention. ( see attached image ). I was planning to scrape / sand away the loose paint, fill the gaps around the panel edges with some kind of acrylic caulk ( flexible ), possibly fill the gaps between the stiles / mullions & bottom rails with 2 part filler or PU glue then prime the bare wood areas before repainting. I'm a lousy painter so would be grateful to hear any thoughts / advice about this. Any recommendation for a good scraper for this type of job would be welcome. Thanks for any advice.
