Hi have painted a room nude quite a few times I found it a lot easier to do the painting also it is quite easy to get the paint off your skin.
I did get caught once doing a girl friends house when she came back a day early.
For what it's worth, I do everything in the nude- it is what we do as nudists. I've recently bought my own motorhome and done some conversions to bring it up to my exact needs. Most of the sawing and timber work was done nude in the garden and it only required a pair of shorts to take the bits out to the vehicle on the road to get them fitted into place, also done nude. Some years ago, I did some substancial room painting for a lady friend on the express condition I'd be naked. She didn't approve of nudity, but didn't have to view me while we chatted and simply didn't mind finding something to do which didn't include being in the same room. That didn't stop her from bringing in the odd refreshments or supplies while I was working. Her only concern was me being seen from outside as the windows didn't have curtains on them. As most of her neighbours were away at work or only passing by, which she was invited to confirm by going outside and seeing for herself, fully dressed, she got used to my total nudity and included my clothes washing with her own domestic tasks. That she didn't want to be naked herself, is not an issue at all. She knew what a naked man looks like of course, and if she had any ideas about comparing me to them, she kept them to herself. Her only expressed interest was about my foreskin, she had only seen circumsized men previously and I was able to show her mine and it's operation as an education. Where is there any difficulty or problem in this example or any other situation. That is just life, and we're all a part of that.
I always paint nude and garden nude, unless there is a safety issue! I try not to frighten the neighbours. My divorced neighbour has seen me nude and she doesn't seem to mind. I am unsure whether her 10 yo son has though.
I have an old house that was built back in 1925. I do all the work on the house naked. Painting with latex is easy to wash off. Oil base the trick is rub yourself and Vaseline first. Its fun but the dust clings to you but it also helps. I have somebody wash it off later
