Uch well no worries Neil, mine will need to keep till the better weather and late nights babies I do the same. Would love to take mine off the run to do it it in one go. Done the o/s sill, and inner arches during the summer, so will move on to the the other sill and a few minor holes here and there. Then probably time to start all over again. There will be more throughout the year, so you'll be welcome at those when you finish ;0)
