    This may seem a pretty trivial question but I would be interested to know what method people use to get a clean finish on the border between glass and wood. I have a couple of doors to do with 6 panes of glass in each.

    Do you mask? Are you just so good you can get a clean line anyway or do you just go for it and then get a clean line once the paint is dry by using a scraper? Just done a couple of windows and I have found it easier to use a scraper than all the hassle of masking on each coat.

    is the glass flat and clear? if so use waterbased/acrylic paint and paint away until your hearts content, when dry clean paint off glass with a razor bladed scraper.......do not try this with an oil based paint as it will not work.

    What seems to be the problem with this? I have a wooden conservatory made from redwood, and painted with oil based exterior paint. When I do a repainting job on it, I invariably drop paint on the glass or it runs a bit, but I leave it for a week or so and scrape it off with a razor blade. I've never had any difficulty getting rid of it, and have never scratched the glass. I guess it depends on how thick the paint is and whether it's completely dry when scraping commences. If it's even slightly 'wet', the scraping method doesn't work well, but you can always take a second stab at it a few days later, by which time the remaining smears should be dry enough to come off cleanly.

    You are obviously DIY, oil paint doesn't dry in a matter of hours as does acrylic. Unlike DIY'ers I haven't got weeks for the paint to suitably harden, I am a professional painter and do not make a habit of badly cutting in!;)

    If using water base paint, then use a quailty synthic paint brush, will make it all much easier.

    Thanks for all that. Water based paint and flat clear glass. Looks like I'll be staying with the scraper. I find it strangely satisfying, as long as I have a keen edge.

    Often small gaps between the glass and timber frame/bead

    Sometimes putty used or just glass bead, or sections of putty have dropped out

    If small gaps or ragged edge of putty, small bead of caulk around the glass, wipe off excess with a damp cloth. Allow caulk to dry, overnight if you can

    I find a small slant cut brush good for cutting in these glass panes with a small overlap onto the glass

    If I'm painting small framed glass, I paint on the frame close but don't worry being exact, some gets on the glass. I use a cocktail stick to 'draw' round the glass/frame meeting when wet, which separates the joint.. When dry you can then push scraper/stanley blade flat towards the frame and the paint just falls away.
