Finally managed to put a coat of blue on the whole tub, had a disaster yesterday primed one side and top coated another only to find that both paints came up in little blisters due to moisture on the surface, the primer settled back but the blue dried with a surface like sandpaper which required half a day rubbing back to smooth. Increased thge workshop temperature and upped the speed on the de humidifier also went over both sides with a heat gun before I started any painting today. Bolted on the pto shaft and gearbox plus a few other bits and bobs ad then spent a couple of happy hours cleaning up nuts and bolts to bolt back the other major components.
