Thanks for that tip Shedders - I may well try it. Anything that avoids reliance on sunlight has to be a smart move when heading into a Northern UK Winter.
Mike - I sincerely hope you have ferocious nostril hair! Composite dust is lethal stuff and you really don't want it in your lungs - more to the point, WE really don't want it in your lungs... you need to live a long and healthy life so we can learn from your techniques.
I don't want to lecture you... but I'm going to...there are some really effective, comfortable and relatively cheap reusable masks available. I use this 4000 Series half mask by 3M.
It is just so comfortable and the seal is so good that you can't even smell vapours through it. It's also available in SA.
OK, lecture over.
Who has also nurtured ferocious nostril hair. You can't be too careful.
