Paragon: Illumination Board Filler

Some areas needed filling due to splitting and delamination from the original cutting and drilling. I use trade Polyfilla One Fill - a weird light-weight filler that is easy to work, can smoothed so flat it doesn't have to be sanded and can be overpainted after 15 minutes if not too thick! Tough and doesn't shrink, I've used it indoors and out.
